1956–1967 Chevrolet Corvette C1 / C2 NOS Spark Plug Wire Grommet Holder #3719963

Available for sale is a genuine General Motors New Old Stock (NOS) Spark Plug Wire Grommet Holder, GM part number 3719963, designed for 1956–1967 Chevrolet Corvette applications including C1 and early C2 models. This original GM service replacement component is a rare and highly desirable detail part for restorers seeking factory-correct engine bay finishing components.

The 1956–1967 Corvette era includes both the late C1 models and the early C2 Sting Ray generation—two of the most important periods in Chevrolet Corvette history. These vehicles are highly collectible and widely restored due to their performance heritage, distinctive styling, and role in establishing Corvette as America’s premier sports car.

The spark plug wire grommet holder is a small but important engine bay component that helps route, support, and secure ignition wires as they pass through designated mounting points. It ensures proper wire organization, prevents chafing or heat damage, and contributes to a clean, factory-correct engine compartment appearance.

Over time, original grommet holders can become brittle, cracked, missing, or deteriorated due to engine heat, age, and exposure to oil and environmental conditions. Damaged or missing components can result in poor wire routing, increased risk of ignition interference, and an unoriginal engine bay appearance.

This component is a true New Old Stock (NOS) GM service replacement part, meaning it was manufactured during the original production era and has never been installed on a vehicle. It retains factory specifications, original materials, and GM engineering standards intended for proper fitment and long-term durability.

Unlike many reproduction engine bay details, NOS GM components provide authentic fit, correct material quality, and factory-correct appearance. This is especially important for Corvette restorations where engine bay presentation and originality are critical.

For restorers, maintaining correct ignition wire routing and detailing is essential for both authenticity and proper engine presentation. Whether restoring an early C1 small-block Corvette or a mid-year C2 Sting Ray, this grommet holder helps complete the factory-original look.

As original Corvette engine bay components become increasingly difficult to source, NOS detail parts like this have become highly sought after by collectors, NCRS restorers, and Corvette enthusiasts worldwide.
