1969–1971 Chevrolet Chevelle / Nova / Camaro NORS Turn Signal Switch Cam (SM18)

Available for sale is a New Old Replacement Stock (NORS) Turn Signal Switch Cam, part number SM18, designed for 1969–1971 Chevrolet Chevelle, Nova, and Camaro applications. This vintage steering column component is an essential part of the turn signal assembly and is ideal for restorers and classic Chevrolet enthusiasts seeking correct-period steering system hardware.

The late 1960s to early 1970s Chevrolet lineup represents one of the most iconic eras of American muscle cars. Models such as the Chevrolet Camaro, Chevrolet Chevelle, and Chevrolet Nova are highly collectible and remain popular for restoration and performance builds. Maintaining proper steering column function is critical for safety and originality.

The turn signal switch cam is a key internal component of the steering column switch assembly. It interacts with the turn signal mechanism to return the lever to its neutral position after completing a turn and ensures proper cancellation of the signal. A properly functioning cam helps maintain safe driving operation and correct steering column behavior.

Over time, original switch cams can wear due to repeated use, plastic fatigue, or mechanical stress. Common symptoms of failure include turn signals not canceling properly, sticking signals, or inconsistent switch operation.

This item is offered as New Old Replacement Stock (NORS), meaning it was manufactured as a vintage service replacement part and has never been installed. These components were produced for dealership and repair use during the era and are valued for their correct fitment and period authenticity.

Unlike modern reproductions, NORS steering components provide original-style construction and design consistency, making them highly desirable for accurate restorations and reliable operation.

For restorers and collectors, maintaining correct steering column components is essential for both safety and authenticity. Whether restoring a Chevelle SS, Nova SS, or Camaro, this turn signal switch cam helps ensure proper function of the steering column system.

As original GM steering column service parts become increasingly rare, NORS components such as this SM18 cam remain highly sought after by restoration specialists and enthusiasts.
