Do you mean cutting a piece off the spindles and enlarging a couple holes in the spindles and center section? Those are the only things I can think of. Everything else just bolts up. If so, if you buy the parts from Factory Five they will be NIB just like anywhere else and will require those mods. I can think of a whole bunch of assembly steps harder than those. Just saying.
