Rear Window Gasket Only – Fits 1973-1987 Chevy C/K & GMC Truck Back Glass

Restoring a classic squarebody?

Here’s the rubber seal you need for the rear window.

This is the gasket only—just the rubber part that holds the glass in place.

Fits Chevy C/K and GMC trucks from 1973 to 1987.

It’s brand new from BAG, part number WBL1135 or WBL 1135 GBF.

Made in Taiwan, so quality rubber.

It’s black, flexible, and ready to install.

The OE part number is WBL1135 if you wanna cross-reference.

Placement is rear window, obviously.

It’s 18 inches in length (that’s the measurement for the part, not the glass, obviously).

Comes with a 90-day warranty.

Whether you’re doing a full restoration or just stopping that leaky wind noise, this gasket is the piece you’ve been hunting for.

No glass included, just the seal.

Get your classic sealed up tight!
