Seal the Deal on Your Corvette Restoration with a New 1963-1978 Antenna Base Gasket
When it comes to restoring your Corvette, it's the little things that separate a good project from a great one. This 1963-1978 Corvette Antenna Base Gasket is a small but crucial piece that keeps your Corvette’s original style intact — and its body protected. Designed as a direct replacement for GM part number 3820672, this gasket provides a perfect, weather-tight seal around your antenna base for non-power antenna models.
Over time, original antenna gaskets dry out, crack, and shrink, leaving your Corvette vulnerable to moisture intrusion, paint damage, and even rust. Installing a fresh gasket not only restores a factory-correct look but also helps preserve your Corvette’s value and beauty for years to come.
Why This Antenna Base Gasket Matters:
-
Functionality: Forms a tight, reliable seal between the antenna base and body panel, preventing water and debris from causing costly damage.
-
Authenticity: Crafted to match the original GM specifications for a clean, factory-fresh appearance — critical for detail-oriented Corvette restorations.
-
Durability: Made from high-quality, weather-resistant rubber for long-term protection and flexibility, even under harsh conditions.
