8 3/4 742 Center Section Rebuilding

Use an impact gun, be it pneumatic or electric for the pinion nut. A big wrench to hold the yoke, I held mine by hand, but it had been apart before. Tank or brake clean the case. I wouldn't blast it unless its super rusty. Any automotive grade paint will work with proper prep and follow the directions for cleaning and a primer if called for. A 742 is a 742, use what manual you have.

Dr Diff is the way to go. Cass is awesome!
