All I have is a wire welder , think that would work ?If you're really carefull, you can drill some 1/4" holes in the panel where the spot welds are
and mig them in without too much heat damage to the surrounding paint. Prime and paint
the support before you weld it in. You'll have a minimum of touch-up later. Good luck!
Can’t see picsYes! as Dadsbee illustrated with the Excellent pictures, you can mig that baby right in!
