Yes.
The only difference is that the '76 and up caliper uses a 2.75" piston, whereas the '73-'75 caliper uses a 2.6" piston. Can be a decent upgrade. The calipers can be had with a metal or phenolic piston, I like the metal ones.
Exactly! The ‘76 calipers went to using the same 2.75” piston that the B/E bodies has started using in ‘70. The E’s and some of the B’s used pin style calipers vs sliding, but they all had the larger piston. And starting in ‘76 everything, including the A’s that formerly used 2.6” piston calipers, went to 2.75”. So A’s, and the B/R/F/M/J cars used 2.75” piston calipers from then on. All of those calipers are not the same, there were still pin style calipers and some of the B body calipers, while sliders, have the brake hose inlet in a spot where it will interfere on an A body. I believe the 73/74 B-body sliders are the ones to avoid for A's.
I ordered a set from Classic Ind. and their site showed 76 and up. Their tech said it looks like a typo in the description, but show be good to go. We will see when they show up, made by OER.
