The upgrade (2.80-3.80 posi) I put in last night. I am now embarking on the engine work, so it probably won't be street worthy again until Saturday. The thrid member is a newer third member. It has a drain plug on the front, my original one did not. The company offered a $100 core return with the drain plug type, but my original becomes a door stop without. The install was very easy. Thanks to everyone for their advice.
I will post back what I think of the rear end. I will say that with the original rear end at 45-50 mph I drove in 2nd gear (TH 350) a lot, just to have some power.
