I have a dual rear wheel LBZ with a flatbed and I want to lighten it up a bit. I really have no need for dual wheels. What would need to be done to convert it to single wheel? I already have a set of PYO's for it off my other truck. Is the front as simple as removing the adaptors? Also its a 2wd if that matters. I put this in the sled pulling forum, I know you guys are experienced in converting singles to duals.
