The quarter panel extension is an important exterior finishing piece on the rear of your 1971-1972 Ford Mustang Fastback. Located where the rear quarter panel wraps into the taillight panel area, it helps define the body shape and complete the transition between the side and rear of the car.
A damaged, missing, or incorrect extension can leave visible gaps, disrupt the rear body lines, and make fresh paint or trim work look unfinished. This direct-fit replacement includes the molding needed to help restore the selected side with a cleaner, factory-style appearance.
Restore clean rear quarter panel lines on your 1971-1972 Mustang Fastback with a direct-fit extension complete with molding for the taillight panel area.
