Rear Bumper Grommet

This rear bumper grommet is a fully molded rubber part designed to replace factory numbers #408642 and #408643. It fits various 1937-1938 Cadillac Series 60 and 65, as well as Oldsmobile F-37, L-37, F-38, and L-38 models. The grommet measures 4" x 2-1/8" outside, with a 1-5/8" x 9/16" inside hole, and 1-5/16" height. It is interchangeable with another common type (#70-0144-29), so be sure to confirm fitment for your vehicle.

Installation is straightforward: this part fits into the rear bumper mounting holes to provide a cushioned seal, reducing metal-to-metal contact and preventing wear or rattling over time. Using a proper grommet ensures your bumper stays securely mounted and protected from vibration damage.
