Klhansen - i will tear into it and see what I find, thanks! Luckily I don't need truck for groceries.

3B - Thanks for info. When I take it apart I will measure and post dimensions.
Hopefully it is straight forward. I hope it is a real seal and not felt.

I guess they are Eaton axles? I have 2 '56 2spd rear axles here but from Fords. They look very similar.
