rear brake swap question

My two cents from my personal experience...

I've swapped complete brake set ups between 1974 7.25 and 1968 B-body 8.75 and between 1973 A-body 8.25 and 1970 A-body 8.75. The swaps involved the 10x2.5, 11x2.5 and the 10x1.75 brake set ups. All were direct swaps with no modification and all were large bolt pattern axles.
