I found the whole intermediate bearing assembly at NAPA for my '49 3/4 ton driveshaft. Couple things I have not been able to locate:

ball collar shims
ball collar cork seal
drive shaft oil seal

Any suggestions for where I might locate these parts? NAPA did not have a listing.

The shop manual suggests that the ball cork seal be shellaced in place. Any comments on that would be appreciated.
