i know I have seen a B-body 8 3/4 bolted right in a Dak..not sure if it had the perches moved.

but was slighly narrower than stock dak axle and fit a 10' rim with a 10.5 tire in the fenders(not usre if tubs were stock)

I measured the jeep axle I have from a 94 cherokee sport
43" perch centers and axle flange to axle flang was 61" with out the drum on.

anyone know the axle flange to axle flange on the A-body 8 3/4 with large brake axles?

i think the jeep axle and A-body are very close at 61' IIRC

anyone have the flange to flange measurement on a jeep axle with disc brakes??

i want one for the 85 truck as the bed is tubbed and ready for fattys ,this maybe the cheap ticket I have been looking for and disc brakes too boot
