So I have decided I don't like beading between the rear fenders and the body on the 48 and would like to weld the fender to the body and fill to give it smoother lines. I have repaired all of the floor panels,fire wall and a few body panels and they have turned out well. But this looks like a much harder project to get the fit right and then fill the entire seam. Has anyone done this before?
Advice needed.

Thanks in advance
