Any help is needed. My rear license plate bots are rusted on. One of them broke the last time I had to change plates so the plate has been held on with just one bolt for last couple years. Well,, it blew off today on the road. Can't find it. The screw is still there. I can not get the screw out though. It is rusted in place and the other side had just the shaft part of the screw with no head. Any ideas? Can I just drill it out? and if so, what size or kind of bit. I will have to go to the DMV and order new plates but if I can get the front one on the back for the time being it would be great. I tore the rear panel off the hatch but all it is, is a square nut welded in place.
