The area on the A-piller post is the place where the factory placed the VIN tag on these cars. The two holes must have been pre-drilled before the sheet metal was welded together. Then a screw was added with a flat washer to keep away the rust,primer and the finally paint. The reason for that is that the VIN tag was spot welded with one dot on each end and that needed to be against the bare steel area on te A-pillar post.
Of cause I did NOT do it that way so now I need to take of that paint so a spot welding process can take place.
But my thoughts are about the spot welding. Is it possible to spot weld a stainless steel plate against a steel plate with the spot welder going from just one side?
