Help Me Identify This Seal!

[cobrAA]

So my mechanic took out my RB26 but he end up damaging the seal of the cv shaft. Well, we thought it was the seal and O-ring but after looking at Fast and then calling around, nobody could tell me the parts number of this seal and o-ring and one told me that it didn't exist.

So, I speak with my mechanic and then he came to the conclusion that it might be under the differential's part listing. I guess, I'm not the first this happen.

Could you please help me quick. Motor should be put back next week and I need to order these 2 items before!

Try front final drive section in FAST... pretty sure they're in there.
