Hy BlackViking60, the o.e.m. p/n for the standard axle hub cap gasket is 3650732, that did not cross at Napa's site, a search of my FelPro catalogue did not bring up a match in their illustrated section either. Sorry I can't find them for you.
Thats okay! I found that the gasket stuck to the hub cover, on the side that was "missing" so i still have both gaskets. I was worried i lose one when i sent the hub/drum out to be machined. If i can dig up anything on that p# ill be sure to get back to you on it. Thank you so much! Youve been an invaluable help!!
