MP Concept Rear Window Louver, Gloss Black for 2015-2021 Fastback Mustangs Product is used, I purchased this brand new from American Muscle in July 2021. It comes with the rear window louver, the metal pieces that screw onto the louver, and 3M tape that goes onto the bottom of the louver metal pieces that holds it onto the Mustang. This louver is meant for Fastback Mustangs 2015-2021. No damage at all to the louver, slightly dirty from recent use on car. Please see all pictures. Feel free to ask questions!
