This is an original GM heater control for 1967 Chevelle, El Camino, Malibu, SS. Very nice faceplate, these normally have the ends broken out from pushing the levers to far. This will work in 1966 also, some early 66 cars had a plastic outer bezel instead of chrome plated. This is NOT for air conditioning. All original levers that function well and cables work (defroster cable had a small bent and had some drag when moving. See Pictures
