Difference between 70-71-72 dusters...

If I am not mistaken for 70, radio is thumbwheel, Sun visors differ, bucket seats one year common to A,B,E with dual track lock, door panels pattern, seat skin paterns/medallions, grill/emblem on standard grill, no sharktooth in 70, no ridge on trunk, different simpler exterior decals and no 340 engine decal, valiant fender badges, no jack slot in bumpers.
