I recently puechased 2" spacers for the rear of my 05 dually. question is: when you pull the outer wheel off, you slide the spacer on the studs, you run the provided lug nuts up and tighten them and they self align the spacer because of their acorn shape right? now when you slide the stock wheel onto your new spacer the holes in the wheel are slightly bigger than the studs on the spacer. with the stock GM lug nuts there is no way to get the wheel centered perfectly. could I have bought spacers for a 2500 HD SINCE THEY HAVE ACORN LUG NUTS, ANY HELP?
