Series I rear oil seal for MT extension housing | 37167
 

Can't find the part at any shops locally. . . though, I ordered one to the Advance in Smyrna that turned out to be an absolute bust. Anyways, I'm just wondering if anyone has one locally that I can buy.

I think they're the same as the FC. The front seal, clutch, and everything else seems to be shared with the FC. You may also try Paul or DJ since Beck Arnley seems to make most of that stuff and they usually have it in stock at the warehouse. If you need their numbers, just let me know, and I'll get them to you.
