Keep your classic Square Body Chevy or GMC sealed and protected with this 1973-87 Square Body Chevy & GMC Truck Windshield Seal w/o Trim Channel, a high-quality reproduction designed for trucks that originally came without exterior chrome or black lockstrip trim. This seal fits snugly around the front windshield glass, bonding it securely to the cab frame to prevent leaks, wind noise, and vibration while maintaining a clean, factory-style appearance.
Made from durable, automotive-grade rubber, this weatherstrip is engineered to OEM specifications for a perfect fit and long-lasting flexibility through all seasons. Unlike cheap aftermarket reproductions, this seal installs easily and fits properly just like the original GM part.

- Install the seal onto the cab frame first — do not install it on the glass before fitting it to the cab.
- Fit the windshield glass into the rubber channel (a little Windex works great as lubricant).
- Press the glass into place evenly, ensuring full seating for a tight, weatherproof seal.
