The spider gears are GM 1358192 (10 tooth), the side gears are GM 3652344. I already have a new cross shaft and R&P, as well as all new bearings & seals for the diff pinion and axles. If I'm going to rebuild the diff, it does not make sense to use the old worn gears. This 55 1/2 ton diff is going into my 42 3/4 ton rear end, per the tech tip article on this site. Want to upgrade from the 4.55 diff that was OE to 1942 3/4 ton.
