Hub assemblies

A possible solution making you able to use your current hubs would be to find lugs that are slightly larger in diameter.
Measure the holes and the lugs, and try to find some that are 2-4 hundredths larger in the knurl diameter in a length that will work. Buy a few and try them out. Many are available singly and cheap on Rock Auto. Dorman's website is a good place to start.
