I made a set of wheel centering rings for my W350 dually. Heated them up and slid them on. Polished the inside of the wheel slightly for a nice tight fit and BAM, I finally have a wheel that is always centered the way it should be. No more using 2 kinds of lug nuts. WHile I was making these, I had enough material to make some extras. I have enough for 4 more trucks if anyone else wants a set, PM me!
