Does anyone know where to get these outdated oil seals that are used at the end of both the idle and countershaft? Or at least know the correct name?

Thats just a simple 'O' ring, Try a NAPA store. I bought a box of assorted sizes years ago, 100s in there.
Well mine is not an O ring. The grove is flat and about 5mm wide. It looks like a sliced bicycle tube but thicker.
Master Part list 1421118 # 20.0949 calls it Oil Seal.
I can't help but wonder if stacking a few o-rings together would work.
I think those seals were originally leather. I remember using a piece of leather cut to size and soaked in oil on my '37. It worked. Harry

Probably more durable than rubber.
Joe I thought about it too but don't think it will work. O ring grooves are genrally round and it will not seal enough.
Thanks for the tip Harry.
For sealing the counter shaft and reverse idler shaft use cork gasket material cut to fit the square groove and your favorite sealant.

Yes cork is also a widely used sealing method. I think I'll go for that.
Thanks all ;)
Northwest Transmission Parts (http://nwtparts.com/) who sells parts for the transmission supply o-rings for sealing the shafts. They seem to work, but you need to use a de-burring tool or something to chamfer the outside edge of the hole in the case or it will shear the o-ring rather than compress it when you install the shaft.
