The bearing combo can be circumnavigated but most of the 5 on 5 mid 70's GM rotor and one rotor fits a lot of applications, are right 11 and 3/4 in diameter. That would require brackets with the holes for the caliper pins 3/8 of an inch further out from center.

One possibility is to see if you can redrill a set of the 4-3/4 rotors to 5 inch. They would still be 11 inch but that may be the simple solution.
