I would suggest that you install the running boards, bolt down the bed, place the vehicle on the ground with the correct tires and rims on the truck and then place the fenders up to the bed sides. You can take two clamps and clamp the front of the fiberglass fenders to the running boards and then take the rear frame to fender brace and clamp that also to the fender. Now take a few steps back and look at the position of the tire in the fender opening. When your happy with the look of the fender just remove the tire and drill some holes in the bed to mount the fenders.
