Okay so apparently my Barracuda has been hit on the passenger front side at some point in the past. Well rather then fixing it they hid it and now that I am trying to replace my lower valance I am finding how far the damage goes. Turns out the person who "fixed" it used a bolt and nut to attach several of the mounting points. On top of that the bolts/nuts seems as though they were used and rounded. I can not get any power tools in there I have tried a metric wrench slightly smaller and it won't grip the head. I have tried heat and that allowed me to snap the head off of one. Any ideas one the other 2? Options for breaking them or griping or anything?
