The Mustang pillar post weatherstrip is located on the Convertible Windshield A-Pillar & runs from the top of the Windshield to just above the Door Hinge. Over time the pillar post weatherstrip gets dried and hardens causing water to leak inside the car. Replacing them makes for a water tight and quiet ride.
These parts fit: 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992 and 1993 Mustangs.
