Just pull out one of your bumper bracket bolts and get six grade 5 or 8 of the same size but half an inch longer. You also need 1/4 inch spacers that go between the hitch side plates and the bumper brackets, but you can use washers instead. Then you need two 2 1/2 inch bolts with lock washers, washers & nuts to bolt through the step bumper & hitch.
