If you don't know how to shim a rear diff, you shouldn't do it.. it requires special tools. If you don't get it almost exactly perfect, your diff will make a goo whining noise an prematurely wear out the gears. I would see if there is a member that lives near you that knows how to do it, if not.. buy all the parts you need and take it to a good shop.
