Well...with everyone shouting, "Why'd you buy that poser brush guard?" and "Get a real bumper- ARB" I guess it finally goes to show that if wither bumper fails, it ends up in heavy front damage. I would have to say that if the accident was low speed as you say and those bolts sheared off, you'd better get some heavy duty bolts as mentioned and hook it up right.
