The body I have has a lot of serface rust at the interior joint of the roof to the body sides. Also on the outside of that joint(where the belt line bead overlaps the lower body, there is rust dust falling out every now and then. I removed all the 1/4 in. bolts at the seam and found what must of been spot welds every 4 or 5 inches. before I make this any worse than it is, any one recomend away to go?? Don't think you could come down on them with a drill bit.
