Whos running over 700whp on an 8.75?

That's the exact route I went. Got the rearend out of a mid-70's F250 at a pick-n-pull w/ a 4.10 gear, Trackloc, and 1350 yoke. After selling the Trackloc, I swapped in a powrlock, added some Mopar housing ends, and a set of Dutchman axles with 5/8" studs (all parts from Dr. Diff).

You won't regret it! What is the wall thickness of the axle tubes in yours? Mine were 5/16"!!

Did you buy the actual alignment inserts and rod? Or did you just put the shafts and bearings in the ends and use garage tools to get it close and weld it up? I was thinking I'll assemble it all and cut 4 windows in a piston ring compressor and use that to wrap around the housing and the new housing end to tack weld it.
