Differential O-ring size needed

Can anyone give me the size or the part number of the two o-rings that goes on either side of the diff where the axles are?

Its the one that seals the diff on each side, as shown in these pics.

I have a 3.42 diff that I will be selling, but I want to replace the o-rings and reseal it before I offer it for sale.

Thanks for any help.

those are the updated newer part numbers I am showing as well.

also; 89021677 - part number for the anerobic sealer that GM now suggests using on those end-cap O ring seals.

so you put this stuff on the o-rings themselves prior to installation?
