Front Door Glass Bump Stop - '70-78 GM Applications

Rubber stop controls glass travel; many applications use two per door.

This front door glass bump stop is reproduced to factory-style dimensions for a wide range of 1970-78 GM applications. The molded rubber stop mounts low in the door and provides a controlled contact point for the moving window glass, helping establish the intended travel limit and keeping loose glass hardware from striking surrounding components. Many listed applications require two per door; see fitment and the body manual for exact location.

Features • Molded rubber front-door glass bump stop • Lower door-window application • Factory-style dimensions • Provides controlled glass travel stop • Many applications require two per door • Fits several 1970-78 GM models - see fitment • RESTOPARTS® 12-Month Warranty
