In the process of running new wiring to headlights. The original headlight assembly was never really that tight(you could rotate it by hand). I hit it up good with PB blaster and tried to tighten it, but now the bolt just rotates in place and the assembly is loser that it was before. Didn't want to pay the $60 a piece for new headlight, just wanted to replace the bulbs. I can't cut off bolt and get a new one because I don't think I will be able to find one. I tried cutting a notch out on the threaded end and used a flablade screwdriver to hold it in place while i turn the nut but that worked to no avail. Don't have a torch. Any ideas what I could do?
