Rear Window Gasket

This Rear Window Gasket is crafted from the original part to ensure a perfect fit and a seamless seal around your vehicle's back glass. It features vulcanized (bonded) ends, meaning you won’t have to cut or splice it during installation — just set it in place for a clean, professional finish.

• Fits all closed models except Sport Coupe and Sedan Delivery.
• Replaces factory part numbers 4058822 and 5058822.
• Made from high-quality rubber for durability and long-lasting sealing.

Installation Tips: Use the included installation instructions PDF for guidance. Applying a black windshield and body sealant (sold separately) helps secure the gasket and prevent leaks. A scraper/tuck tool can assist in fitting the gasket neatly into the frame.

Handcrafted in the USA and guaranteed to fit your classic Chevrolet or Pontiac model.
