Hey forum, posted here before on subject of wheels for an 06' Fat Boy. Am still looking. Tough decision. There is a rim made by the stealer that I like but it says will fit only 08' an up. It's an 18" inch set-up in which I want to go with anyway. And it comes in the 3.5". I'm guessing because the size of the axle. My question is, is there anything out there to convert to this fitment in which I can put these on the bike? Like a fitment or adapter kit to fit axle sizes? Thanks for any input on this...
