I'm collecting parts for this mod for my 94 zr700. I guess the spindle I need is from a 97 aws4 sled? Would someone have a part #for these? I can't tell the difference between the 4's and 5's on line, is there an obvious visual diff? I also saw lower control arms that had heim joints on them where they would attach to the spindle, would this help the geometry problem with the aws 5 spindles?
