Duster seats

1970 & early 71 - same. Long release button I hinge covers separate from back & these

Late 1971 into 1972 - Same. Short button & hinge clovers on piece with back.

At some point in early 72 that style was phased out & the foams are not interchangeable due to the springs being part of the newer foam all in one piece.

My bucket seats came out of a 71 340 duster I owned in the 80's I didn't realize then that it had a 72 interior in it, It wasn't till I pulled it's interior out of storage years after I had to scrap the car and saw October 10, 1971 ink stamps from the Lyons trim plant(Lyons Michigan)on the back of all the interior door panels by then the title and tags were long gone but it had a 71 tail panel and a rallye dash

Anyone have some good rear and side shots of 70 buckets?
