Animal, Rickson will make you a set of 22. 5's with the original bolt pattern so you won't need an adaptor. I don't know if this is limited to only dually style of if it includes singles, but Rickson is the way to go. I have considered it myself but I spent a ton on Dual Designs package a few years ago so I'm stuck with those for awhile.
