This is a picture of a 51 GMC that sets on a 74 Cadillac Sedan DeVille chassis. The frame was shortened and narrowed and the front fenders had the wheel opening enlarged 3" for tire clearance. The fender lip (bead) was cut off, moved out, and welded back. It was necessary to add in a section as the bead was longer for the larger opening.
