Those are b/e body 2.5" brakes on there... Do those require a longer axle to clear vs. the standard a body shafts???
I believe the backing plates are offset so any A-body axle will work. Just need the correct drums.... I put those brakes on my 69 Dart, used standard axles. From Dr. Diff..... Or just put narrower shoes on. Not a great cost....
