Thanks 3B! I was able to get the wheel seals using the National P/N you provided. That was the last piece I needed to complete my rebuild on the rear end.

It took trips to 5 different parts stores to get the wheel seals and I ended up getting 1 seal from the first and 1 from the fifth, buy I got it done. The Tank (my daughter's name for the truck) is back on the road.
