1960–1964 Chevrolet Corvair & Corvair FC NOS Turn Signal Switch Cable #3777469 / #3780490

Available for sale is a genuine General Motors New Old Stock (NOS) Turn Signal Switch Cable, GM part numbers 3777469 and 3780490, designed for select 1960–1964 Chevrolet Corvair and Corvair Forward Control (FC) applications. This original GM service replacement component is a rare and increasingly difficult-to-find part for restorers seeking factory-correct steering column and turn signal system components.

The Chevrolet Corvair was one of General Motors’ most innovative vehicles, featuring a rear-mounted air-cooled engine and unique engineering unlike any other American production car of its era. Introduced in 1960, the Corvair quickly gained popularity for its distinctive design, handling characteristics, and advanced technology. Chevrolet later expanded the Corvair platform to include the Forward Control (FC) lineup, consisting of the Greenbrier Sports Wagon, Corvan panel van, Rampside pickup, and Loadside pickup.

The turn signal switch cable is an important component within the steering column assembly. It helps transmit movement from the turn signal lever to the switch mechanism, allowing proper activation of the vehicle’s directional signals. Reliable operation of the turn signal system is essential for safe driving and maintaining factory functionality.

Over decades of use, original cables can become worn, stretched, corroded, damaged, or broken. Steering column components are often subjected to constant movement and vibration, eventually leading to wear that can affect turn signal performance. During restoration projects, locating genuine replacement parts for early Corvair models can be particularly challenging due to the vehicle’s unique engineering and limited production numbers compared to other Chevrolet models.

This component is a true New Old Stock (NOS) GM service replacement part, meaning it was manufactured by General Motors during the original production era and has never been installed on a vehicle. Unlike reproduction parts, it retains the original factory specifications, materials, dimensions, and engineering standards intended for Corvair applications.

For collectors and restorers pursuing factory-correct results, NOS components remain the preferred choice. Original GM service parts provide authentic fit, appearance, and operation while helping preserve the historical integrity of the vehicle. Small steering column components such as turn signal cables are often overlooked, yet they play a vital role in overall vehicle functionality.

Whether you’re restoring an early Corvair coupe, sedan, convertible, station wagon, Greenbrier, Corvan, Rampside, or Loadside, this NOS turn signal switch cable offers an excellent opportunity to install a genuine GM component designed specifically for these applications.

As original GM Corvair service parts continue to become scarcer, authentic NOS components are increasingly sought after by collectors worldwide. Properly functioning steering column controls contribute to both safety and driving enjoyment, while original replacement parts help maintain the authenticity and value of a restoration.

This turn signal switch cable represents not only a functional replacement component but also a genuine piece of Chevrolet history. It is ideal for restoration shops, Corvair enthusiasts, collectors, and anyone seeking original GM parts for a high-quality restoration project.
