To identify a REAL '64 GTO, you need to contact Pontiac Historic Services (PHS).

It will cost you $35.00, but it's an absolute guarantee of accuracy - unless the VIN tag has been changed.

You can also get a reproduction of the window sticker for $28.00.

This is THE source for verifying all things Pontiac.
theres nothing on the body/ trim tag that says GTO? My aunts father has her 1964 GTO convert, that she bought new in '64, she gave it to him when she got married to my uncle. It's all original, white, 4spd, not shure but I think it is a 389. never been restored but always been garaged and has less than 30k on it, and is still showroom mint, he also has her brothers '67 Mustang fastback, 289, 4spd grabber blue, same condition as GTO, never restored ither. he died in Vietnam
