Any Idea where to even start looking for a set of 1972 seats?
regarding the frame 70-71 same, 72 is on its own
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.
