Lock in the Movement: 1968–1982 Corvette C3 Headlight Housing Rear Link Pin with Grooves
If your Corvette's pop-up headlights hesitate, shift awkwardly, or seem misaligned, the issue could be a small part with a big job—the rear link pin. The 1968–1982 Corvette Headlight Housing Rear Link Pin with Grooves is a precise, purpose-built component designed to keep your C3's headlight door assembly aligned, secured, and moving like it should.
Why This Part is Essential
Mounted at the rear of the headlight housing, this grooved link pin connects the linkage arms to the actuator and frame. It serves as a pivot point and fastener, guiding smooth headlight motion while maintaining structural alignment. The added grooves are engineered for positive engagement with the retaining hardware, locking the pin securely in place to prevent unwanted movement.
Over time, original pins can wear, rust, or loosen—leading to misalignment, uneven opening, or even contact between the housing and surrounding fiberglass. This exact-fit replacement restores tight tolerances, reliable movement, and the clean flip-up action that defines the C3 Corvette.

Tech Note: Prevent Costly Damage with Proper Headlight Housing Maintenance
Worn or neglected headlight housing actuator and linkage components may seem like minor issues, but left unaddressed, they can lead to serious and expensive damage. As these parts wear, increased mechanical play develops—causing the headlight housing to shift beyond its designed range.
In severe cases, this excessive movement can cause the housing to contact surrounding painted or fiberglass surfaces, leading to chipped paint, surface cracking, or even structural damage to your Corvette’s front end.
Replacing worn pivot pins, bushings, actuators, and support hardware ensures proper alignment, smooth operation, and long-term preservation of both appearance and function. Address these issues early to protect your investment and keep your C3’s iconic flip-up headlights operating—and looking—the way they were meant to.
