Dave, I have a recent-looking National box with two different modern seals that seem to match up with the Hudson "inners." One seal carries number P02099, the other 103747. Neither has a mfr. name. The box "part ID" sticker carries the ID "35X70X8", and the numbers 1.378 x 2.756 x 0.315, the latter appearing to be the dimensions of these seals in inches.. Maybe a helpful parts store guy can find the source with one of these numbers. Good luck!

Park,
Thanks for the info. I will add it to my "data base"..
I was able to get the inner seals from NAPA. They use SKF numbers.. inners SKF 13710 , Outers were SKF 17310 and the pinion is SKF 17720. Darned numbers are so close, they can be confusing.
