I have a question for all you all. i have 1948 GMC 1/2 panel trk. I noticed some rust blisters at the end of the passanger side drip rail between the rear door and the drip rail. I believe this is a factory seem. When I cut the rusted area out, the support frameing on the inside was also rusted. I won't thing the side metal was touching this frame work. There seem to be a 1/32" or gap. Anyboby else had this proplem?
