Genuine NOS (New Old Stock) ACDelco turn signal switch, Delco #D6203, GM #911051. Still in original ACDelco box (©1995 GM Corp), unused.
Confirmed fitment:
• 1964–1966 Chevrolet (all, except tilt column) — includes Corvette
• 1964–1966 Chevrolet/GMC pickups (except D-D)
• 1965–1966 Buick Special, Skylark, GS (without tilt)
• 1965–1966 Oldsmobile (all, except tilt or cornering lamps)
This is the “stamped Guide” type switch and includes the center steering column bearing — genuine GM sourcing, not a reproduction. This is the correct, harder-to-source original for restorers who want factory-correct parts rather than the aftermarket reproduction switches commonly available (which run $10–40 but aren’t genuine GM/Delco).
Switch shows wiring pigtail intact with all colored leads and connector as pictured. Box shows some edge wear from age/storage.
