C2 1963-1967 Corvette Firewall Hole Plug - 4-Speed

1963–1967 Chevrolet Corvette Firewall Hole Plug – 4 Speed

Restore a clean, sealed engine bay and factory-correct appearance with this 1963–1967 Chevrolet Corvette Firewall Hole Plug – 4 Speed. Designed specifically for C2 Mid-Year Corvettes equipped with manual (4-speed) transmissions, this reproduction plug seals the unused or auxiliary firewall opening above the clutch push rod.

On 4-speed Corvette models, the firewall contains multiple openings for linkage, cables, and accessories. This Corvette firewall hole plug is used to close off an unused hole in the firewall—typically located above the clutch linkage area—helping prevent air, moisture, and debris from entering the engine bay or passenger compartment.

Manufactured to replicate the original factory design, this plug is typically constructed from durable molded plastic or rubber and is engineered for a snug, secure fit in the factory firewall opening. It is built to meet OEM specifications for proper sizing and appearance, ensuring accurate installation during restoration or maintenance.

This component plays an important role in maintaining a sealed firewall, helping improve cabin comfort by reducing drafts and protecting interior components from moisture intrusion. It also contributes to a clean, factory-correct engine compartment appearance—especially important for detailed restoration projects.

Designed as a direct-fit replacement, the plug installs easily into the existing firewall opening without modification, making it ideal for Corvette restoration, firewall detailing, or replacing missing or deteriorated plugs.
