1984-1996 Seal, Windshield Header and Pillar. This is the weatherstripping that seals the leading edge of the targa or convertible top and the leading edges of the side windows to prevent wind noise, water, and other debris from entering. This one-piece weatherstrip starts at base of windshield pillars and travels up each pillar post and across the top of windshield frame. The complete removal of old weatherstrip material is critical to a successful installation.
