Installation tips

To install, align the plate with the factory underside mounting points and anchor it with the appropriate hardware.

Check that the seat belt hardware sits flush and that the plate is seated securely to avoid misalignment with the belt buckle or latch.

Rather than a generic reinforcement, this Outer RH plate is a precise, OEMreference component designed to mirror the original GM design. It helps you preserve the Corvette's authentic look and performance, while giving you confidence that your passenger seat belt system will behave as intended in routine driving and in the rare event of a collision.
