Not that it shows but the design for the air dam and side skirts on this panel van were to have been strapped to the mounting brackets with bungee cords like a light-plane landing gear. With 2-3" of travel ground strikes would abrade the edge of a wooden plank. The air dam was to be curved plywood.
