Axle again...8 3/4"

The small bolt pattern 10" brakes are narrower than the 10" brakes on latter axles not to mention the difference in the bolt patterns.

The a-body axles that have been modified to accept big bolt pattern wheels usually use a C-body axle shaft that has been cut down or new custom axle shafts. The distance from the end of the axle tube to the face of theflange on the axle shaft is to short for the 2.5" wide brakes used on the big bolt pattern axles including the 8.25.
