I plan to do a write-up on this build as a contribution to the site. Maybe something you guys can sticky. I see tons of questions regarding rear-ends in the drivetrain forum and it might have some pointers others can follow. This was a complete bulletproof 12 bolt truck build I did myself. They are still weak rears and there is no proof that this one will hold to my future plans but we will see.
4.56
studded mains
solid pinion spacer - no crush collar
welded axle tubes
girdle cover
3 in axle studs
Everything is complete except for the axle studs. I need to buy a 9/16 drill bit and make the holes a lil wider and the moroso studs will press in.
