Can anyone please give me all the bearing part numbers for final drive bearings on 1969 oldsmobile Toronado
Or Is there somewhere where I can get part numbers
I also would like a new 43 tooth diferential ring gear if possible
All the part numbers are un readable

The 2 thin factory pinon seals have metal humps on the backs of them, they install metal to metal which makes a air gap between them that vents to the small pin hole in the housing. #1 seal stops the differential grease in the carrier the other # 2 seals stops transmission fluid from the trans. ( you never want grease getting into the trans ) The trans & differential both build pressure inside them so the 2 seals are better then just one seal. also GM made a tool to put them in just the correct spot so as not to block the vent weep hole. So if trans fluid or differential grease comes out the hole you know which seal is shot ! The bad news, good luck finding them seals if you do they cost an arm & a leg ! So that one New seal is wider & will block the weep hole but its better then 2 old hard used seals !
