Stripped bolt on firewall for Voltage Reg.

A fast and cheap way to fix this is to stick some strands of copper wire in the hole, and just insert the screw. Just strip some insulation and unwind the strands, and stick it in the hole. It effectively makes the hole smaller, conducts the ground well, and can be trimmed up so it isn't seen. I always would mean to go back and do a better job, but every time I did this, it was fixed for good.
