Rear end build!??!

[Capinoy123]

I'm going to tear apart my 4 bolt rear end and put some 3 bolt gears in there... but i don't have any specs for the rear end!! like backlash, and pinion depth those kind of specs! can anyone help? Please...?

I don't remember the exact numbers, but I used my Hayne's manual for the specs. Mostly it's just putting some grease on the differential gears and looking for an even wear pattern across the teeth. My perfect setting ended up being the exact same pinion spacer as it already was. By the way, I have a bunch of extra factory washers for the rear end build if you need some.
