These guards are formed from 3/16″ thick mild steel to fit the curvature of the rear portion of the quarter panels. Coverage starts from the inner lip of the bed rail and ends just above the bottom inner lip of the quarter panel. Please note that these cover the side only and do not wrap around the rear or cover the tail light area. They come bare metal (~16″ long) and without mounting holes. The trailing edge is shaped to approximately match the curvature of the tail light panel. No mounting hardware included. They are designed to either be used by themselves or can be welded to our Early Bronco Tail Light Covers for superior corner protection. They can also be welded to (or simply butted up and bolted down) our Early Bronco Upper Quarter Panel Guards for that ultimate body protection. See the Gallery for customer installs.
