There is a heavy tube fits over the floating hub with long bolts on larger diameter shafts that screw down over the stock lugs. The first owner had the fenders widened when the dually kit was put on. Needs some surface rust attention and the LR fender is tweaked. I have a replacement RF fender. For some reason that one has rust through. Before I get all crazy on the body, I need to get the 401 and T400 ready to role and install a couple fuel tanks we got from Ristow.
