Available for sale is a genuine General Motors New Old Stock (NOS) Ignition Switch, GM part number 1116703, AC Delco number D-1400A, designed for 1968 Chevrolet Chevelle applications. This original GM service replacement component is a rare and highly desirable part for restorers seeking factory-correct electrical system components for their classic muscle car restoration.

The 1968 Chevrolet Chevelle is part of the highly respected second-generation Chevelle lineup, a model year widely regarded as one of the most popular eras for Chevrolet’s mid-size performance platform. Known for its aggressive styling, strong engine options, and widespread use in both street and drag racing, the 1968 Chevelle remains one of the most iconic American muscle cars ever produced.

The ignition switch is a critical electrical component that controls power distribution throughout the vehicle. It activates the starting system, ignition circuit, and accessory functions, ensuring proper electrical operation when the key is turned. A properly functioning ignition switch is essential for reliable starting, stable electrical performance, and safe operation of the vehicle.

Over time, original ignition switches can wear out due to internal electrical arcing, heat buildup, corrosion, and mechanical wear from repeated key use. Common symptoms of a failing switch include intermittent starting issues, loss of accessory power, electrical interruptions, or complete ignition failure.

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 original factory specifications, materials, and engineering standards intended for correct fitment and long-term reliability.

Unlike many modern reproduction parts, NOS GM electrical components offer authentic internal construction and correct terminal design, ensuring compatibility with original wiring harnesses and dashboard configurations. This is especially important in vintage muscle cars where electrical accuracy is critical for performance and reliability.

For restorers, maintaining originality in the ignition system is essential for both authenticity and dependable operation. Whether restoring a base Chevelle, a Super Sport (SS), or a high-performance small block or big block configuration, using correct GM components helps preserve factory functionality.

As original GM electrical service parts become increasingly difficult to locate, NOS ignition switches like this have become highly sought after by collectors, professional restorers, and muscle car enthusiasts aiming for factory-correct or concours-level restorations.
