Can i just get a set of big bolt axles from a 8 3/4 donor A-body and get the drums to match?




There was never a factory big bolt pattern A body 8.75"

Dr.Diff here on the board can sell you brand new axles for the 8.75 with the big bolt pattern

Depending on your engine and if you don't already have a 8.75...could just use a '73 and up big bolt pattern A body 8.25 too
