70' Duster rear end, trans upgrades

There's a local Mopar race at US131 on Sept 9, so my goal is to have it rolling by then.

I had a Dana 60 housing laying around, but I decent to put a "8-4/4" in it. I built the housing a while back for someone else, but they changed wheel combo mid way so ended up too short and I've been debating what to do with it. So I said hell with it and I'll put it in here.

The case will be a thru bolt aluminum, 35 spline spool/axles, 3.70 pro gears. The springs I moved in already for the previous owner and I believe are older HD springs I believe. They'll suffice for now but down the road will be Calvert springs and assassin traction bars.
