1997-2004 C5 Windshield Header - Pillar Weatherstrip Mounting Pins 25016383
Ensure a factory-correct seal with this set of 1997–2004 Corvette Windshield Header and Pillar Weatherstrip Mounting Pins. These plastic fasteners are essential for properly securing the weatherstrip that spans the windshield header and A-pillar area on all C5 models. Each side uses two pins at the lower ends of the seal, while the top header features two additional mounting pins—for a total of four required. We've included two extra pins in this 6-piece set to ensure you have replacements on hand in case of breakage during installation. Reusing aged or broken fasteners compromises weatherstrip alignment, leading to water intrusion and wind noise—this GM-style solution delivers a secure and clean installation.

Weatherstrip Care Tip
Weatherstrip seals are prone to drying and cracking—especially on older Corvettes. Regular maintenance with non-petroleum dielectric silicone grease keeps rubber seals elastic, prevents sticking, and protects against UV damage and extreme temperatures. Apply a small amount to a soft cloth and wipe over rubber seals monthly. This treatment extends the life of weatherstrips on doors, window seals, sunroofs, trunks, hoods, and convertible tops. Avoid petroleum-based products, which accelerate deterioration and surface cracking.
Because Details Matter
Small fasteners often get overlooked during restoration—but correct mounting pins ensure your C5’s header and pillar seals perform just like they did at the factory. Avoid wind noise, leaks, and frustration with the correct OE-style solution—plus two bonus pins for peace of mind.
