I got the rear out of the 88 and into the 90GT. I think the 3.73 with the 4l80 will work better than the t-5 did. I know it isn't much of a difference but I am going to put the 3.55 rear into my 88 notch this weekend. It is leaking slowly so I am going to crack it open while I have it out first to drain it and reseal it and drop in some fresh fluid.
I wish I had the time to swap in the 5 lug axles before I put the rear in but I was running out of daylight and I needed to get it back on the ground. I have it all snugged in there for now. I need to replace/repair some things so I will get back under there when I get time and torque everything down. I really want to start cleaning the engine bay and under carriage soon. Next I can prep the inner fenders and start filling the holes and putting in the new panels. I need to see what the price is on some 18 or 16 ga material first to determine if it is worth while to buy SRP's.
