Does anyone have a layout diagram or sketch to properly position the center exterior side wall mounted support bracket that gets spot welded to the exterior of the bed sides? the front and back are easy to layout but the center would need to be more precise to properly fit against fender. The steel is new for the sides and doesn't have bolt holes yet for the Fenders. Layout for fender bolt holes are needed as well. 1951 chevy 3600 Long bed
