The quarter panel extension is an important exterior finishing piece on the rear of your 1964-1966 Ford Mustang. Located where the rear quarter panel meets the taillight panel area, it helps define the rear corner shape and complete the factory-style body line.
A damaged, missing, or incorrect extension can leave visible gaps, disrupt the rear body contour, and make fresh paint or bodywork look unfinished. This direct-fit replacement helps restore the selected side with a cleaner, more complete factory-inspired appearance.
Restore clean rear quarter panel lines on your 1964-1966 Mustang with a direct-fit extension built for the taillight panel area.
