how to guide for 7 1/4 to 8 3/4

You may want to purchase the following parts depending on condition of these on donor car, and how far you wanna go. Here's a list of what I replaced and parts I purchased:
rubber brake hose, axle vent screw, rear axle brake lines, 20 axle/carrier nuts, a set of BBP axles from dr diff, inner axle seals, pinion seal, yoke straps, U-bolts, shock plates, shock washers, gear lube, 2 new U-joints,
I also bought new drums, brake hardware kit with adjuster kit, and new brake shoes.
Do you plan on cleaning up the housing and carrier, backing plates?
You may have to get the driveshaft resized.
I ended up getting more parts and farther into it then I initially thought I would. But I tend to be a little obsessive/compulsive....lol
The work itself is pretty easy, you shouldn't have a problem.
