The seats will swap physically, but the tracks are different. The American used an "L" hook-up at the front of the stock track and all Concords and AMC after about 70 used some configuration of a flat front part of the bracket. The seats themselves will fit on the tracks but they may sit too far foreward. I have a set of 75 Hornet seats that I bolt into various AMCs while those seats are being fixed. Those Hornet seats have been in my 70 AMX, 68 Ambo, 65 American, 64 American, 60 Classic and will be in a 71 Hornet next week. If you like monkeying with tracks, all AMC seats interchange easlily.....Russ __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
