My truck has been parked for the last few months since I broke the pinion gear. I finally got it driving again
While it was parked I I was looking for a used Dana 80 to swap in.
While searching I went ahead and pulled the transmission and replaced the oil pan seal kit, rear main seal, pilot bushing, throw out bearing, and replaced the Sachs clutch disc. Also the clutch fork had some small cracks in the pivot sockets, I welded them and greased them before re-installing it.
Then I rebuilt the getrag with new main bearings, syncro rings, seals and an input shaft. I then replaced the shaft coupler and seals between the getrag and T-case.
After I found a Dana 80 I got the driveshaft shortened 2" and found that my stock leaf springs had some bad rust pitting under the top plate. I decided to just install the leaf springs off the 2nd gen as well as convert my truck to use 2nd gen style shocks and I also installed the sway bar.
The way I installed the springs and hangers I eliminated the 6" lift block and used a 1" block.
Now that all that is taken care of it rides way better, the 2nd gen rear drum brakes seem a bit stronger, and the axle wrap is almost gone. Plus the clutch and transmission are smoother.
Drives like a completly different truck now, so far I'm very happy with the results.
