1969–1973 Chevrolet Camaro & Corvette C3 NOS Delco Ignition Switch (Tilt Column) #1990096 / D-1423A

Available for sale is a genuine Delco-Remy General Motors New Old Stock (NOS) Ignition Switch, GM part number 1990096, AC Delco reference D-1423A, designed for 1969–1973 Chevrolet Camaro and Corvette C3 applications equipped with tilt steering column. This is a rare factory-correct electrical component for classic Chevrolet performance and sports car restorations.

The late 1960s and early 1970s Chevrolet Camaro and Corvette C3 models represent one of the most iconic eras in American performance history. The Camaro became a symbol of the muscle car era, while the Corvette C3 introduced bold styling and continued Chevrolet’s legacy as America’s sports car. Both platforms remain highly desirable among collectors and restoration enthusiasts worldwide.

The ignition switch is a critical component of the vehicle’s electrical system. It controls power distribution to the ignition circuit, starter system, and accessory functions, allowing the engine to start and operate correctly. In tilt-column applications, the switch is specifically designed to integrate with the steering column mechanism for proper alignment and reliable operation.

Over time, original ignition switches can fail due to worn electrical contacts, heat damage, corrosion, or mechanical fatigue from repeated key use and steering column movement. Common symptoms include intermittent starting issues, loss of accessory power, or complete ignition failure. Replacing a worn switch is essential for restoring proper electrical function and dependable vehicle operation.

This component is a true New Old Stock (NOS) Delco-Remy 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 engineering standards intended for correct fitment and long-term reliability.

Unlike modern aftermarket parts, NOS GM ignition switches provide authentic internal construction and correct terminal design, ensuring full compatibility with original wiring harnesses and tilt-column assemblies. This is especially important in high-performance vehicles where electrical reliability is critical.

For restorers, maintaining originality in the ignition and steering column system is essential for both authenticity and safe operation. Whether restoring a Camaro RS/SS, Z28, or a Corvette Stingray, using correct GM components helps preserve factory performance and reliability.

As original GM tilt-column ignition components become increasingly difficult to source, NOS switches like this have become highly sought after by collectors, restoration professionals, and muscle car enthusiasts aiming for factory-correct or concours-level restorations.
