Dana axles were available in these trucks, LMC shows them as the posi-trac axle. But if the chunk comes out the front like a Ford 9", then it's not a Dana. It's probably the Eaton axle. I did a little digging and found that pinion seal number on the National seal cross reference. Just had to drop the K at the end. National shows it as a GM seal and crosses it to their 6818. They show that seal to fit '53-'62 with the HO33 and HO35 axle. Hope that helps.
