The fronts changed for 1969 probably because of the fins they added for heat dissipation. They will still fit a 65-67. The rears changed after 1975 because the U.S. braking standards became more demanding for the 1976 models. Rear brakes on A-bodies became larger for 76, even Jeep CJ5 models had to be upgraded to front disks for 76, again as part of the more demanding new standards.
