Bit of a small update, been having a problem with a leaking axle, ended up taking it in getting the bearing etc replaced a second time, still leaked and started making a noise from the bearings in the diff.
Took it back and turns out part of the LSD is broken off the side. Looking at having one machined or buying a new one. Also changing the ratio from 3.9 to 3.5 while the diff is in pieces. Turns out its an old LSD from the 70's still has plenty of life in it yet.
Ordered my outer shells for the three piece wheels finally. 8" on the back and 7" on the front
