1964, 1965 or 1966 Barracuda ? Cant seem to find what I need to on the VIN! .

Interesting. I've not see a tag like that. My 64 Valiant is plain silver on the body between the driver door hinges. Where is this located?

Waiting to see what others weigh in with

Good luck
Its inside the drivers door. Towards the back seat. Whatever that piece is called :)
