Available for sale is a genuine Delco-Remy General Motors New Old Stock (NOS) Ignition Switch, GM part number 1116579, AC Delco reference D-1412, designed for 1960–1962 Chevrolet D-D Series Trucks and StepVan applications. This original GM service replacement component is a rare and highly desirable electrical part for restorers of vintage Chevrolet commercial vehicles.

The early 1960s Chevrolet D-D Series trucks and StepVans were built for heavy-duty commercial use, including delivery, utility service, and fleet operations. These vehicles were designed with durability and reliability in mind, making them popular choices for businesses and municipal fleets during that era. Today, surviving examples are widely restored for collector use, vintage commercial displays, and specialty vehicle builds.

The ignition switch is a critical electrical component that controls power distribution to the ignition system, starter circuit, and accessory functions. It allows the engine to be started and ensures proper operation of the vehicle’s electrical systems. In commercial vehicles like StepVans and D-Series trucks, reliable ignition operation is essential for consistent daily use.

Over time, original ignition switches can fail due to internal contact wear, corrosion, heat damage, or mechanical fatigue from repeated use. Common symptoms include intermittent starting issues, loss of accessory power, or complete ignition failure. Replacing a worn switch is necessary to restore dependable electrical function and vehicle reliability.

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 proper fitment and long-term durability.

Unlike modern aftermarket replacements, NOS GM ignition switches provide authentic internal construction and correct terminal design, ensuring proper compatibility with original wiring harnesses and commercial vehicle electrical systems. This is especially important in vintage work trucks where reliability is critical.

For restorers, maintaining originality in the ignition system is essential for both authenticity and dependable operation. Whether restoring a StepVan delivery vehicle or a D-Series utility truck, using correct GM components helps preserve factory functionality and historical accuracy.

As original GM commercial vehicle electrical components become increasingly difficult to source, NOS switches like this have become highly sought after by collectors, restorers, and vintage truck enthusiasts.
