Just received my Tailbone, and low and behold my buddy decided to get a head start on me and take my OE bumper off, he snapped 7 of the 8 bumper bracket bolts. These things are toast, Ive drilled, tried to easy out, soaked in every rust penetrator known to man and these things wont budge, Ive tried getting behind them with heat and back them out with vice grips.....nothing. My question is, has anyone encountered this problem on a Detours Tailbone system, and can I just drill out those Anchor nuts and just use thru bolts and nuts. Thanx in advance
