Installation Notes and Tips

Verify the vehicle year, make, model, and right-side rear glass position before installation. Compare the existing support’s compressed length, extended length, and socket-style end fittings to confirm match-up. Replace only with the correct application for the rear glass, and inspect the mounting points for wear or damage before snapping the plastic socket connections into place.
