Need Help finding Obsolete Oil Seals!!!

[Crawl]

Hello... I am replacing the Shifter Plungers and Shift Levers (Forks) on my 1968 M-F 180. The Oil Seals needed to complete the repair are obsolete. I have searched many hours online and made many, many phone calls. I have found only three (3) and I need six (6) to complete the repair. The part number is 833541m1 (Nat'l 442316). If you can help in any way I would be grateful.
Sincerely,

Mark

I looked it up in this huge set of books I have, found pretty much what you already know but have some dimensions and an industry standard code that might be helpful.

The skf catalog is what I use all the time.

Quit searching by part numbers. Search by size
