Desperately Need Shaft Seals and Gaskets for C-90 16 F engine

Matt, thank you for providing the continental engine Schematics and part reference numbers. Armed with that information I was able to order seals and gaskets for the generator, starter, tach drive, and oil screen from AC Spruce Canada, and receive free shipping as I also ordered tires and other stuff at the same time. FYI, I was able to obtain the urgently needed seal for the vac pump driveshaft locally and cheaply by providing them with the OD & ID info from the old seal once it was removed. The seal and new style vac pump by Rapco has already been installed.
Also, a big thanks to everyone who provided potential info suppliers of these parts. I’ll retain that in full for future purchases. Cheers all, Bob j.

As Randy suggested, try Fresno first. My experience with them, they don't usually need part numbers, just tell them what you need to fix the problem and they will know the part #. Also , typically you'll get the best price there!

My A2 Aircoupe Continental is an engine that is new to me. Today  my Old retired AME and I removed the old Vac Pump and confirmed oil was leaking from the engine around the shaft drive due to a poor seal. My dilemma now is where do I get a new seal, and also the 2 associated gaskets.
Part numbers and a source that sells these are badly needed.
Any help would be greatly appreciated!
Also, I will soon be needing shaft seals and associated gaskets for both the generator and starter, so my question above also applies to these two items.. Again, I would be great full for any part numbers and tips on where to purchase these. Cheers, Bob
