I’m in the middle of rebuilding my LSD and noticed a very familiar looking car (Mike Davidson) in the first picture when looking at the factory3 instructions. 
It appears that the passenger side outer bearing race was leaking a good deal. Where can I get replacement seals/o-rings for the bearing races? I see that pelican sells a gasket set, but I don’t see the part I think I need.
See the first picture on page 6 of E30_Limited_Slip_Clutch_Disc_Replacement.pdf I’m referring to the bronze ring.
Upon further investigation, it appears the part I’m looking for is the spacer ring.
See #7 from realoem.com. Could this be the source of the leak?
