Where can I get a replacement oil seal for the rear end of the hydramatic trans where the drive shaft enters the trans? I have a 1951 4-door Kaiser 4-door deluxe sedan with a K50 GM HydraMatic Trans. The existing seal has a National P/N of 6010. This seal has a leather material/seal that rides on the drive shaft. I don't know if this is correct for this car or not. The drive shaft O.D. diameter is 1.5". The O.D. of the 6010 seal (that fits into the trans) is approximately 2.156".
I would appreciate any help you can give.
