Got the brakes and pinion gear off of the 12-bolt tonight. The impact drill was a life saver!
Started the dis-assembly of the 12-bolt for inspection. First had to get the drum brakes off with a big hammer:
This is my setup for working on the read axle. Got the cover off without breaking any bolts (sprayed with Kroil for a couple days prior). I can still wheel it around the garage with this setup. Will let it drain over night before doing much more. I have a DVD to refer to for the rest of it. I need to inspect the portion that holds the posi in place. If they are in bad shape, I won’t be able to use the axle as they are matched to the rear axle. So I will need to do some inspection before determining if I can use this and before ordering replacement parts. I do know I will be changing the gearing to 3:73 gears.
