Differential cover gasket

[BuickGN]

What is the GM part number for the rear differential gasket for the TTA?

Viktor part number is 12523445 ... however they been discontinued by GM so not sure how easy it is to find one these days.

You might need to confirm but looks like the Felpro number is RDS 55390, not tried and compared but looks like the correct gasket.

I changed mine last fall. I used Felpro and kept the box. Jan, the number you posted is correct #55390. I havent had any problems with mine. No leaks or seeping.

Jan, I have searched and can't find the thread I made about it. I posted the part numbers and pics of everything. Aggravating.
