70rs/ss, thanks for the fast verification of the rear. I was looking on the left side when facing the ring gear and the only numbers I could find are 30060, and 55 11. Is there a different place to look then where I am looking? I will let this thing apart since it needs the GM additive and I dont have any with me. I still need to work on getting the fill plug out. The guy before me has it all rounded off and it may be a challenge to get out. The truck is a factory 327 with 4-speed transmission. I know that number 55 11 does not sound very right for a ratio. I need to look around more and hopefully find it somewhere. Maybe after a good cleaning with break cleaner I can see it easy. Thanks again.
