I polished up 24 1/2-20 RH lug nuts that I had sitting around in a coffee can, which had been removed from old cars in favor of new shiny ones. I put them on my wifes 04 Dakota, and they fit perfectly. The ones I took off the Dakota were the crappy ones with the chrome cap on them. The Dakota has aluminum wheels from the factory, and the taper on the lugs were the same between factory Dakota nuts and the ones I replaced them with.
