I have a 66 dart gt and they have vinyl covered metal Hard backs on them.
they could be 65-66 plymouth valiant or barracuda seats
this is 66 darts seat configuration
Still trying to get a ID on these, I can't seem to find any with ashtrays like these. The C body's did, but they are nicer seats. The studs that bolt to the floor pan are 8 3/4" and 18 3/4", are these early A dimensions?
