Preamble
The information provided here is taken from Turning Wheel articles written by Fred K. Fox.  The text is rewritten to include some of my own observations, ideas and interpretations of what I read.  The charts are for the most part rearranged reproduction of information found in those issues.  Any error in translation of the TW information is the total fault of the author of this page.  Please feel free to point out any error you might find or to suggest additional information you think might be helpful.  Use the “Contact Us” page from this website.

Disclaimer: This page is not intended to be a complete reproduction of the work Fred has done and I would encourage you to seek out copies of his many TW article on GT Hawks as they contain a significant amount of detailed information way to detailed for me to present here.

Simple grille with a square pattern and no grille emblem.  Side horizontal signal lights
Grille has horizonal bars with a rectangular pattern.  A Red, White, and Blue emblem.  Round amber signal lights with clear bulbs at the ends of  mesh background side grilles.
Same grille pattern, but the horizontal bars are recessed and painted flat black.  New center Gold Hawk emblem.  New circle "S" hood ornament.
 
General Restoration Information:
Note in the photo's above that both the 1962 and 1963 body color (White) is showing through the grille.  All 1963, 1964 and most 1962 GT Hawks should have had the area behind the grille painted flat black as shown in the photo of a 1962 GT Hawk at the left.
 
Except for a few early 1962 GT Hawks, all 1962, 1963, and 1964 GT Hawks should have the inner portion of the air intake under the bumper painted a low luster black.  The outer portions should be body color.  The lower hood locking mechanism was also painted low luster black.
 
In looking at many photo's of GT Hawks, I noticed that many do not have front bumper guards.  Others  have them closer to the center, then others (1963 photo above) show them further out.  I wondered about this, and this is what my research has uncovered.  All three years the front bumpers were optional equipment.  Item No. 68 in 1962 & 1963 and 71 in 1964.  In close examination of the 1963 front above I discovered that there were no holes in the bumper where factory installed bumper guards would have been mounted, thus these must have been dealer installed or added by one of it's owners.  Some information I picked up on the SDC forum indicated that front bumper guards were optional, that factory installed bumpers were inboard and dealer installed were outboard as there were no bumper holes to install them inboard.  If you have any thoughts on this let me know using our "Contact Us" page on this site.
 
The wheel color on all GT Hawks (all years) was Pebble Sand on off-white color.  Only two styles of exterior mirrors were offered for 1962 to 1964 GT Hawks, Stratoline (AC-2918) and Strato-Vue (AC-3188).  The correct radiator and heater hose clamps are the spring wire type, except for the lower radiator hose clamp on the water manifold which was the flat metal type with the small screw and nut.
 
All GT Hawks are equipped with 289 cubic inch V8's.  In April of 1962 the full flow oil filter system was adopted.  Duel exhaust and finned brake drums were standard equipment.  The engine block, heads, pan, air cleaner canister, pulleys, power brake unit, power steering unit, and electrical components (except alternator) were black.  The valve covers and automatic transmission dip stick handle were painted yellow.  The oil filler cap (or caps), fan and the oil dip stick handle were painted orange.  The air conditioning compressor was natural metal color.  STP decals are found on the oil filler caps (breather caps).  The Avanti Jet Thrust engines were the same as above, except the valve covers, oil dip stick handle, air cleaner canister and R2 air inlet were chrome.  R2 superchargers were Orange from the factory and black if rebuilt by Paxton.  The R3 & R4 engines blocks, heads and pans were red, none were factory installed in any GT Hawks.  Any 1963 or 1964 GT Hawk would be correct if equipped with the Avanti dress up kit AC-3421, which included chrome valve covers, oil breather caps and dip stick handle.
The left photo is from an early (not full flow oil filter) 1962 GT Hawk engine and the right photo is from a 1963 (full flow oil filter) GT Hawk engine.
Not sure about the 1962 engine valve cover decal, but the 1963 engine STP decals are correct.
 
Grand Turismo Hawk History 1962 to 1964
 
Current Status:
Recent history for GT Hawks indicate that while the early Hawks are going down in value, the GT Hawks are in fact getting more expensive to purchase.  The probable causes might be that there were far fewer of them made, especially 1964.  The GT Hawk production started October 30th 1961 and ended in December 20th 1963 (64V-20197).  In addition, these cars had a lot more of the driving comforts available, like power steering, power brakes, front disc brakes (mid 1963), factory air conditioning and power seats.
 
The Birth:
The GT Hawk styling is done by Brooks Stevens Design.  A lot of the work on the GT project was done by Gordon Kelly, Stevens design department director, but Stevens was deeply involved in the project, acting as liaison between his company and Studebaker's design chief, Randy Faurot1.  The the project is given to Stevens by then Studebaker President Sherwood Egbert, with a nearly non-existent budget and very short lead time.  Stevens is going for the European-inspired, clean look.
Foot Note1: TW March 2008
1962 GT Hawk:

The exterior.  The hood from the older Hawk's remained (for 1962 only) minis the chrome air scoop, but retaining the raised area.  However, a new much lighter front grille that closely resembled that of a Mercedes-Benz is added.  The Gran Turismo would draw on American influences as well, with a roof line that looks heavily inspired by the Ford Thunderbird.  A chrome edge that runs from front to rear, at the top of the bodywork, similar to that on the contemporary Lincoln Continental.  The new taillights look like they may also have been borrowed from Lincoln.  The deck lid is given a faux "grille" overlay (to hide the grooves of 1956-61 deck lid), something similar is seen on the rear of the Lincoln Continental.  The rear window is nearly flat and recessed.  New nameplates and emblems, along with a new grooved rocker panel molding, complete the changes.  After a three year hiatus, the GT would come back as a hardtop.  Stevens's extensive yet inexpensive modifications to the body completely removed 1950s-style tail fins and body side trim of past Hawks, creating that clean luxury look still in high demand today.
 
Stevensnew interior, with a modern instrument panel, could be ordered with a full complement of large, easy-to-read gauges, in the correct driver's line of sight.  The gauge portion of the dash is a three plane affair with wood grain background.  A new metal overlay would cover the rest of the dash.  The top 2/3rd's of the dash was padded to serve as a crash pad.  Door panels have vertical vinyl pleats on the top, a center metal panel and carpet on the bottom.  This treatment continues on into the back seat panels.  The GT featured front bucket seats and a console, befitting a grand-touring car.  All the seats were upholstered in either cloth and vinyl or all-pleated vinyl.  Sadly, the 62's vinyl was of very poor quality and quickly cracked along the pleats.  It doubtful any 1962 GT Hawk exists today with usable original upholstery.  1962 GT Hawks were the only year the seat pleats were horizonal.
 

Mechanically the GT Hawk remained very similar to it's inheritance.  The 289 cu. in. V8 engine is used, along with a Flight-O-Matic, manual four speed, or standard three-speed transmission. The manual three-speed was available with the optional overdrive.  The chassis was very similar to the 1961 Hawk.  The greatest 1962 mechanical change would be a mid-year change making the 289 a full flow oil filter engine.
 
Tells:
From the front, small rectangular signal/running lights are seen in the two small side grilles.  The surrounds should be painted body color, many of the 1962 GT seen today have chromed surrounds which are not correct, but look nice.  This is the only year, that there would be no emblem on center grille and the grille pattern is simple series of squares.
 
From the side, “Gran Truismo” door badges are present, without the later years red/white/blue badges.  For most of the year, the standard full-wheel covers have a black scallops on the outer edge, with a black lazy “S” in the center on a red center back ground.  The plastic spears on the front fender are about twice as high as the ones used on the next two years would be, and are not back-lit.
 
From the rear, the faux "grille" overlay checkered pattern is painted black, while the smooth area containing the script “Studebaker Hawk” is not painted.  The deck lid badge is a chrome circle with a gold Hawk in the center.  The new tail lights have body painted housing with chrome trim around the lens.  Most 1962 GT Hawk, if equipped with a radio have a center mounted rear deck-lid antenna.  This was because the new trim on the front fenders would not allow for a cowl mounted antenna.  This issue was addressed late in the model year when a cowl mount antenna was designed, so 1962 GT Hawks are the most likely ones to have a rear antenna.
 
From the interior, 1962 would be the only GT with horizontal seat insert pleats.  A metal dash overlay is seen on the right 2/3rds of the dash, although some early 1963 models would also feature this overlay until the inventory is used up.
 
Restoration:
 
Hubcaps:  In 1962 there were no less then four different hubcaps that could be correct.  Initially the hubcaps used were exactly the same as 1961 Hawks and Larks, black “S” on chrome center with black peripheral scallops (AC-3071).  Shortly after production began they switched to red centers (AC-3276).  Two optional set were available at extra cost, Air-Flo (AC-3277) or Air-Strut (AC-3280).  Both (photos left & right) seem to be fairly rare.
 
Sidebar:  In February of 1962 Studebaker began giving out personalized dash panel nameplates to each new Hawk owner.  This practice would continue (if requested) on all GT Hawks until the end of production in Dec. 1963.

The photo shown on the left is from a 1963 GT, the name has been removed.  We do not have an image of a 1962 name plate, but expect they were all the same.

1963 GT Hawk:

Tells:
From the front, new mesh side grilles, new headlight rims are a combination of paint and chrome with grooves on the inside.  The grille now has five prominent horizontal bars and a new red/white/blue grille badge is located on the lower drivers.
 
From the side, “Gran Truismo” door badges are present, but now have new red/white/blue badges behind the script.  The standard full-wheel covers are exactly the same as last years, except the center back ground is silver rather then red (AC-3405).  The plastic spears on the front fender are about half as high as the ones seen last year and are back-lit when the headlights are turned on.
 
From the back, there is a new red/white/blue deck-lid badge with a gold hawk in the center. 
The overlay is modified, the “Studebaker Hawk” lettering is much larger and the smooth background is painted black.  The waffle pattern squares are painted silver.  The rear deck-lid radio antenna is an option, but seems most buyers opted for the new available cowl mount.
 
From the interior, the seat insert pleats are now vertical.  The metal dash overlay from last year are seen on early cars, after 63V-K6-1328 this portion of the dash would have woodgrain overlays.  (See photo on the right)
A black steering wheel with a new horn ring is introduced.  1962 GT Hawks did not have a horn ring.
 
Mechanical changes for the 1963 GT Hawks, the generator is replaced with an alternator and the drum brakes were again self-adjusting, last done in 1953.  Hawks equipped with disk brakes (mid-year) would have a brake reservoir attached to the firewall, but would not use the duel master cylinder introduced this year on the Larks.
 
Restoration:
Two of the most frequently discussed restoration issues, other then the dash features above, involve the red/white/blue door badges and the front signal lights.
 
The colors given here are from left to right as you face the badge.  A red/white/blue badge with gold base should be placed on the drivers side, while a blue/white/red badge with gold base should be placed on the passenger side.  On 1964 GT Hawks, the badges would be red/white/blue on a chrome base on both sides. Most of the photo's I have seen of 64's follow the 1963 pattern, the reason is unknown but supposedly incorrect.
 
The early 1963 parking/turn signal lights (left photo) had flush mounted amber lens (part #1353542) with clear bulbs. At serial number 63V-11587 (right photo) the lens housing changed, having grooves on the inner sides similar to the the headlight rims and a new recessed amber lens (part # 1355019) with clear bulbs are used.  In 1964 the lens would change to clear with an amber bulb.  Clear lens were used on 1963 exports, but the best information indicates that all 1963 GT Hawks should have amber lens with clear bulbs.  These photo's also show the new headlight rims which are a combination of chrome and paint with the interior grooves.
 
 
Side Bar: The side grille are are now for looks only as no air can go through them.  They are a newly designed shape and thus required a modified hood, so 1963 and 1964 GT Hawks cannot use the prior Hawk hoods (1956 – 1962).
 
R1 & R2 Jet Thrust Avanti optional engines were available for installation in all 1963 GT Hawks.   Installation of an R series engine is identified by a rectangular badge placed just below the air vent door on the front fenders.  The badge stated either “Avanti Powered” (R1) or “Avanti Supercharged” (R2).  In addition to the engine options offered early in the production year, special packages wereintroduced in April of 1963 called “Super Hawks”.  The R1 package (Item No. 46) cost an extra $371.70.  The R2 package (Item No. 46A) cost an extra $581.70.  It was originally intended that either Super Hawk package would have the original grille emblem replaced with a round R1 or R2 badge.  However, there are examples where the grille badges did not appear on these special edition cars.
On the grille badges on the right, note the "Stars" in the Red section,  they would not be there for the 1964 grille badges.
 
The following chart lists the items which came standard with these packages.

18 R2 Hawks were assembled in Canada, none were Super Hawks. Eleven of them had Flight-o-Matics and seven had four-speed manual transmissions. Sidebar: The number of sixes or 259 V8's powered GT Hawks is unknown, but we do know that what ever may have been manufactured was sold outside North America.
 
 
1964 GT Hawk:

Tells:
From the front, the embossed Hawk on the top of the grille surround is removed in favor of a stand up circled "S" emblem (hood ornament).  The grille pattern is similar to 1963, but the vertical bars are slightly recessed and painted flat black.  There is a new central grille emblem, a gold Hawk on a brushed chrome base.  The side grilles, actually slightly reshaped, now curve around toward the inner edge and have no vertical component.  The signal light lens are clear with amber bulbs.  The R series round grille badges are redesigned.  The surrounds and headlight rims are mounted with black rubber cushions between them.
 
From the side, the red/white/blue badges are on a chrome instead of gold base.  The horizontal molding on the “C” pillar has black paint in the grooves.  There are new full-wheel covers (AC-3155).  The Hawk “birds” and the “Gran Turismo” script have changed from gold to chrome.  R series fender badges have changed from rectangular to oval.
 
From the rear, the faux metal over-lay is gone, there is a new smooth deck-lid, finally 1956 to 1963 grooves are gone.  This change requires a new chrome “Studebaker Hawk” script for the new deck-lid.  The taillight housing are completely chrome plated.
 
On the interior, the pleats are removed from the upper dash crash pad.  A new lower crash pad is added below the radio and glove box.  The chrome metal door inserts are replaced with wood grain panels, the upper door pleats are horizontal instead of vertical and those red/white/blue emblems seen on the outside of the doors are now on the interior door panels as well.  The background around the gauges is black instead of wood grained and new chrome trim surrounds each section of the three plain instrument panel.
 
Mechanical changes were slim in 1964, most significant was the addition of R3 & R4 packages, while available no factory R3 or R4 was sold.  The badges were produced and sometimes seen and added to R3 or R4 clones.  However, several options were added for R1 & R2 packages, which include transistor ignition system, exhaust headers and a heavy duty competition clutch.
 
Restoration:
One of the unique features of the 1964 GT Hawk, was the optional new black or white vinyl “Sports Roof” that could be added to the front ½ of the roof.  We don't know how many of this option was purchased, but have one example in our club in Ron Bell's 1964 GT.
 
Besides the new standard full-wheel covers (AC-3155) for 1964, the Air-Flo's were discontinued, but the Aero-Strut style was still offered, as well an a new wire spoke version.  Halibrand “mag” wheels were available from dealers.  The Halibrand's have recently be made available and I have seen them installed on a local 1964 Avanti.

Wheels on the outside were painted an off-white color called Pebble Sand. Most if not all of the wheels were painted black on the inside. No two-tones were offered from the factory during the 1964 model year. Studebaker called their enamels “Sapphire-Luster Exterior Finishes” and claimed that they never needed waxing.

Day of Month
A two digit number representing the day. (12=12th day of the month)
Studebaker adopted an all new engine numbering system in 1964. The first Letters in the string will identify the engine type. The next letter will identify the month built. The third number “3 or 4” will identify what year, 1963 or 1964. The last two numbers will represent the day of the month. In this system, any domestic engine type built on the same day have the same engine number, which means for example a GT-Hawk, Lark, and Taxi Cab having a 289 V8, built on January 3rd would have the same engine number “PA403 (decoded P=289, A=Jan, 4=1964, 03=the 3rd day of the month. Only export engines would have a suffix (an added number at the end) to identify nth engine for that day.
