as for the bumper, get a hammer and a towel. put the towel on the bumper mount you need to bend so you dont put a bunch of marks on it, and then tap away until it lines up. as for the heel guards, what bolts are you talking about? the ones that attach the heel guards to the frame or the ones that attach the heel guards to the pegs? i going to assume that you mean the ones holding the heel guards to the pegs. see if you can use a breaker bar to break them loose or get some big guy (dad, friend, etc) and see if they can get them loose. if all else fails, get a dremel and cut off the head of the bolts and pull them out (they do have a nut on the end of them, right? sorry just havent worked on my heel guards in ages!) if you cut the head of the bolts off, then measure for new bolts that are long enough to mount through your nerfs, pegs, and heels and give you a good amount of thread on the other side to put the nut on. i recommend washers and a good amount of lock-tite when you do this too. i had to get longer bolts when i got the ims pegs and it was a pain because lowes didnt have the right size i needed so i had to go to a specialized company in town that sells fasteners and the like. well, good luck and let us know if you need any help.
