I'm trying to get wheels on the rear that match the front...they are only available in 10" and 4" or 5" bs...am running 8" now with 4" bs. Was hoping to find someone running the same because I know how calculations work. Not going to bet over a thousand bucks on calculations. Instead of spending over a grand for correct wheels I probably will end up doing what Randy mentioned...go buy a cheap wheel, mount tire on it, Double Nut it, and check fitment. I just thought someone here may have the same setup. Thanks for all the ideas.
