i dont have a tap and die set, but i cant use a nut and bolt because the bolts go inside the metal bumper and it is cosed on all sides so i cant get my hand in there to put a nut on, but i may have to go buy a tap and die set, but the metal bumper part is very thin probally only 1/8 of an inch would a tap and die set still be usefull?
