explorer 8.8 in an a-body: experience needed

I am keeping mopar with mopar I picked up a 8 3/4 housing and axles from a 65-67 b-body for $75 which is roughly 3" wider than an a-body and is easy enough to make up in wheel offset I also picked up a 742 housing 3.55 clutch style power-loc for $100 so there are plenty of deals out there.
