do the marlin crawler bumpstops work(MC-13256, Poly Bumpstops $39 (pair))? And would I need new shackles or would the shackle plates work (MC-13216, 6 Inch Plate, $6 each)? I already took a hammer to the front fenders cause my 31x10.5's were rubbing cause i have them on wider rims. But other than that i don't think i have any more questions
