1966 Big Pontiac headlight switcvh
 

Looking for a NOS/used headlight switch for a big 1966 Pontiac, PN 1995138. Also fits 1963 T/4 - T/8 and 1967 Catalina, Executive and Bonneville's and maybe others. Do not need knob and attached rod. Would also buy a used switch connector for this headlight switch. Trying to stay away from the new headlight switches as they seem to frequently require the use of jumper wires.

You are wise to avoid the "counterfeit" switches, the original Delco were excellent.
Very easy to clean up & lube, they used white lithium grease from the factory.
They had a wide interchange in '66, easy to find.

If you are near PHX, when I was there about 18 months ago, Desert Vally Auto had several B bodies to pull from.
