Lots of interruptions, but I'm slowly making progress;

I picked up the used rear end from a local Mopar hobbyist known to have salvage parts. Pulled it out of a pile of semi-rusty rear ends. Had to measure each one to find the right size. May original was 54". We found tons of 56" and 57". I settled for the only 55" we could find, it should fit and the leaf spring perches were at the correct 44".

I realized that I had to have it with the axle shafts to fit the 55" housing so he gave me those with it..
Yep, I got the correct brake backer plate.

Two weeks and I had the rusty housing sandblasted, painted it, let it cure and cleaned out all the old gunk inside.

The axle shafts that came with the new rear end need new bearings, I talked with Cass yesterday and ordered what I need (Dr Diff)... I'm looking locally for a gasket for the 8-3/4" 10-bolt case...

I'll update with whatever difficulties I encounter putting this thing back together again.
