What car do u have?? I know that on a 6th gen there is no bolt that u can injur without being able to remove it. Are u talking about the long bolt that goes through the bottom hole of the strut? If so thst bolt has a nut on the end of it so if u break off either end u can simply punch it out using a screw driver and buy a new one from the dealership. (I'm referring to the 98-02 accords as I don't know how the others are configured)
