I'm also thinking that while I have the front 60 apart, I'm going to convert from 1/2-20 wheel lug studs to 9/16-18 wheel lug studs, to match the rear. I can either drill out/attempt to press in Dorman 610-278 wheel studs into the hubs that I have now, or switch over to a late 80's F250 HD Dana 50 hub, which already uses that same wheel stud. Everything else from a dana 60 is supposed to line up on the dana 50 hub.
Or, I may not need to drill out the current hub if there is enough tolerance. According to Dorman, the hole should be .017 to .027 smaller than the size of the knurl. I'll have to take one of my hubs apart and measure how big the stud hole is with my digital caliper and see if it's within tolerance. The 610-278's are .620 at the knurl, so I'll be hoping for a range inbetween .603 and .593. In comparison, the 610-279's that are stock on the 79 Ford D60 are .602 at the knurl, which means it's hole should be .585 to .575 Hmmm, looking at those numbers, it's likely that I'll have to drill the hub out. A 39/64" drill bit is: .609. A 19/32" is .593. So the 39/64" would probably be the best bet.
As far as mounting the wheels goes - I have to either drill out the rectangular valve stem hole to accept a round valve stem, or fork over about $200 to get 4 of the original versions that are used on the wheels. RIght now I'm thinking I'll drill them out. Just need to determine the correct size.
