how do I tighten the bumper? I looked under the bumper, and their are these black "knobs" with washers around them, and if you push them in, they will come back out to where they orginally were. is that even what I need to do to tighten it? If so, how do I do it?
yeah mine has a little rattle to it now too because of my system i was thinking of finding some thin peices of foam to place so that it will remain tight i guess ill buy some of those plastic rivet dealies too, u think theyll have them at like autozone
