Any ideas how to get a stock bumper off with the trailer hitch still on. I cant get access to the middle four bolts on the inside. I will replace the bolts if I have to, no big deal, but I want to keep the bumper in good shape. The outside ones just snapped off when I tried to loosen them. I wouldnt care if the middle ones snapped, but I cant even get to them! Any ideas. Remember the part of the bolt you can see on the outside is rounded like a rivet, and DOES not turn. Only the nut on the inside turns. For any reason this is an 85 Suburban. Thanks Ken H. '86 K5 in parts 1-ton 44 TSLs 454 BBC, 350 trans, 205 transfer Rust free in Michigan!
