I completed sucessfully
Thankyou all for everything, the emails, faxes with very helpful infor. I replaced all 3 seals before putting in the rear differential. Everything went well. The gear oil plug required a 14mm hex bit and I couldn't find it at Sears, so I end up buying a 14mm bold from the hardware store and bend it to use as a tool. Anyway, the rear differential works good now. Thanks again everyone!
