I have a 67 Chevelle Malibu I need a new hazard switch. Does anyone know where I can get one? Do I have to get the whole plastic piece that the turn signal mechanism is a part of, or can I just get the hazard switch and just replace that? I want to keep the car original

Not sure on the 67s but it's early for me. Maybe someone else knows.

Are you talking about the little chrome knob that screws into the turn signal switch assembly?
