8 3/4 assembly instructions

I am in the process of assembling my 8 3/4 but honestly don't know the if there is any shim process or set up for gear lash . I am a boat mechanic and boats don't have differentials Haha. Is there a book or website to go for assembly instructions ? I have an empty housing that has been narrowed for my 69 Dart along with axles ( narrowed so I can get some bigger tires in them fender wells ) plus I just purchased a " 489" third member with 3.23 sure grip . None of this has ever been put together plus want to get info on green bearings since I plan on installing disc brakes .
Google Richmond Gear instructional videos there is good information there and also some youtube videos will pop up. Hope this helps Cheers
