Casting Number
Carburetors
The part number for the 1965 Carter AFB 4-barrel carburetor was found on a metal tag mounted on the carburetor air horn. For the Tri-Power carbs, the numbers were stamped on a plate and mounted on one of the carburetor mounting screws.
The 4-speed manual Tri-Power setup received a mechanical linkage that actuated the two end carbs; automatic cars were vacuum equipped. This car has a dealer-installed Ram-Air setup. (Thomas Short Photo)
Distributors
The 1965 distributors had the part number stamped and mounted around the distributor shaft.
Intake Manifolds
On 4-barrel engines, the part number is stamped or cast into an intake runner. On Tri-Power manifolds, it can be found on the center and rear intake runners.
| Engine | Part Number |
| 4-barrel | 9778816 |
| 3×2-barrel | 9778818 |
Exhaust Manifolds
The part number for the exhaust manifolds is generally, but not always, found on the outer face of the manifold.

The transmission codes are:
On the Super Turbine 300 2-speed automatic, the transmission code was stamped on the low-servo cover on the passenger’s side of the transmission or on a metal tag.
The 3- and 4-speed M20 and M21 manual transmissions were used on the GTO and, generally, but not always, had the part number stenciled on the transmission case on the driver’s side of the case, at the rear of the cover. The code number indicated the type of transmission and the production date.
An identification code is marked in yellow paint on top of the case on 4-speed transmissions: W stands for wide-ratio and 9 stands for close-ratio. On the 3-speed Tempest (Muncie), the letter X indicates a heavy-duty Muncie and is marked on the passenger’s side of the case. The letter S identifies a midyear (March 1) introduction of the 3-speed manual Dearborn transmission.
1965 Rear Axle Identification, Codes and Ratios
In 1965, differential codes were stamped on the back passenger-side axle tube. The codes identify which axle ratio was used and if the axle was equipped with Safe-T-Track.
The GTO has the following items as standard and were not available on other LeMans models: the vinyl-trimmed assist bar over the glove box door, a GTO emblem located to the left of the assist bar, and a GTO emblem mounted on each door.
Exterior color codes can be found on the cowl data plate located on the driver’s side of the firewall.
The hardtop and coupe were also very stylish, especially with the Cordova vinyl roof. Note the 6.5 emblem on the front fender, while the GTO was placed on the rear fender.
