My truck is an 09, the HD bumper is from an 11. The bumpers are not the same from 99 to 13.
Okay, I'm a complete idiot because this still doesnt make sense to me. There doesnt seem to be enough metal on the bracket to trim away in order to allow the bumper to move down to meet the cap.I just trimmed the bracket that bolts to the frame so that it could sit lower. Then using the side supports I opened up the holes that go to the truck frame so the sides have support still.
