Here is a very nice used original NAPA Muffler and Shock Center Mechanic's/Technician's Fender Guard Protector made by EPPCO Enterprises Inc. out of Cleveland, Ohio.  It measures 36" long by 24" wide made out of a vinyl rubberish type non-slip material.  Very good used condition.  Several scrapes & scuffs.  No rips, tears or gouges.  Thanks for looking.
