Got my dash, door panels, kick plates, front pillar post covers, and stiffener plates in back with new vinyl from the body & paint shop with a piece of vinyl I do not recognize. Please see attached photos to see if anyone knows where it gets installed or not part of car. Piece is 1-3/8" W x 45-1/2" lg and has 9 studs with washers and castle nuts. Any suggests will be acknowledged. Thanks
