Our tire carrier bolts to the rear bumper crumple zone and ties into the factory tow receiver with both tubing and several pieces of plate. To make two of the plates we cut up an old beer, er, soda box to make a template. Then we used a plasma cutter to rough cut some 1⁄4-inch plate for the carrier. We then cleaned each bracket up with a 41⁄2-inch angle grinder with a flap wheel. The last step before welding the plates on was to drill several 1⁄2-inch holes for rosette-welds.
