In a 1969 GTO Judge, the vehicle identification number (VIN) plate is located on the top of the instrument panel and can be be seen through the windshield on the driver’s side of the car. It is a 13-digit number that can be broken down into sections to tell you everything you need to know about the car that you own.
Locate the car’s VIN and write it down. The first number of the string of numbers should be a “2”. This “2” tells you that the car is a Pontiac.
The next two numbers should be a “42” combination, if the car is indeed a GTO. Any other numbers would tell you that the car is not a GTO: A “33” means that the car can be a 1965 to1970 Tempest, a 1971 LeMans T-37, or a 1971 LeMans; a “35” means that the car is a 1965 to1970 Tempest Custom; a “37” number tells you that the car can be a 1965 to1970 Tempest LeMans or a 1971 LeMans Sport; a “39” means that the car is a 1967 to 1969 Tempest Safari.
