Default How many??? Differential questions

my differential is about gone and I have purchased a good used one that will hopefully get me by for a year or so then I can rebuild the original and have it built even stronger. Before I install the used diff I want to replace all the seals and O-rings... I know i will need (2) two axle seals part # 88996703, do I need (1) or (2) side cover o-rings part # 89047953? What about in between the trans and the diff? Isn't there another seal there? Any help on what I should replace during the install would be a great help. I am going to get the stuff from GMParts house and try to save some money.

Thanks so much,

Sully

Mine is leaking from that area. I have a 6 speed and the leak is from the front of the diff where the torque tube bolts on. I assume there is a seal.

Somebody will pop in here with the service manual I'd think

There is an o-ring between the tranny and the differential.
