We matched the holes in the bracket to the bedrail and the floor of the truck. After a coat of primer and paint we were ready to bolt the bracket in place (use washers on both sides). We added a 3⁄4-inch hole in line with the center of the wheel and slid in the 9-inch bolt. Note the 1⁄4-inch hole in the end of the bolt for a padlock. The pipe was threaded into the base plate and cut down to about 7 inches total.
