Just a heads-up..... I wanted 68- 69? seats for my 65 but didn't realize the seat springs could vary. The seat frames are about the same height, but my actual seated height is 1 or 2 inches higher because of the springs. I not sure if PO altered the springs or factory specs changed. I realize the foam is bolstering the outside, but the insert seems lower and angled more towards the back than pics of other 65-66 seats i've seen.
