Injection Pump Booster Pump Seal, where?

1971 M35 A2. According to rebuild tag on IP, rebuild date 1989. I was getting about 1 gal of diesel in the oil per 120 miles or so. I pulled the injection pump and replaced the two o-seals on the head (thanks Bottleworks).

Next I pulled the booster pump off the IP and took it apart. The seal there seams tired. I took the housing by NAPA and they measured as best they could (with the seal still in the housing). Best they could figure was it might be NAPA Seal # 4231 and it was about 1000 miles away. Before I go and order it, and pay extra for shipping, does anyone know where I could get "the official" seal for the booster pump? It is the seal that keeps the diesel and oil apart as in the attached pic. I have called a few places and, it seems to be a hard one to find.

Also, I have the TM9-2910-226-34, but there seems to be no parts version.

I got a part number of 5330-470-6695 from the drawings.

This crosses to SE1034 AMBAC part number.

The drawing is on page 194 B-5 Part #3 if I have this right

and the part is referenced on page 182

SEAL. PLAIN. ENCASED: fuel pump driven gear SE1034 (01843).

I am not sure how helpful this will be. I can also provide a repair and parts service for the AMBAC pumps (American Bosch)

Thanks all. I got the original seal from e-bay:
http://www.ebay.com/itm/ONAN-AMBAC-...024?pt=LH_DefaultDomain_0&hash=item3f3ffd6248
It went in easily after I jacked up the engine. Just needed unhook the air intake and jack up the front motor mount...
However, I attempted to remove the steering column and that did not work and I broke the horn wire and the steering gear bearing.
Does anyone know where to get this bearing balls and retainer:
Plastic carrier with balls is P/N 400076A1 or 10896762 or 3110-00-232-6123

"White Owl" has all the parts needed to repair the steering gear. I know as I recently just did my gear.
