Question about chrysler rallye wheel viniques and a disc conversion

They are just 73-76 A body disk brakes.

The only differences are
- the rotors have the 5x4” pattern added to blank rotors
-the rotor hub is turned down some so it has a smaller diameter (still won’t fit all drum wheels)
-the calipers have 2.75” pistons, which came on the B/E bodies and ‘76 A bodies.
