Can I get some help decoding this info plate? I’m new to this area. I know it’s a 1967 GTO. It has 51k miles and appears to be mostly original.

Im trying to figure out the proper engine trans from factory.

Thanks in advance!

The 12D would indicate it was built in four week in December. The 2KZG Indicate its AC, three speed auto with a console. You would need date codes to see if the engine is the original.

The Pontiac, Michigan and the Kansas City, MO cars were far heavily coded relative to the options on the vehicles. But even these plants did not include all options that were on a vehicle on the tag. To truly find out which options were actually on the car from the factory you should contact PHS. Pontiac is somewhat unique with Pontiac Historic Services (PHS). Pontiac Historic Services can perform this service for 1961 through 198(8) model years. (Information for post 198(8) models will continue to be handled on a no-cost basis by the Pontiac Customer Assistance Center at 1-800-762-2737) . They can send you a copy of your build sheet indicating each item that was originally ordered with the car, its dealer invoice amount, and the dealer number it was shipped to, plus a whole lot of other interesting information. To get your car’s information just send the VIN with $35 to:
