Original Headlight/Charging switch rusted or cooked? Don't make the mistake of purchasing that aftermarket Chinese junk switch that's out in the aftermarket. It doesn't fit correctly in the AC instrument boxes. We are the only company on the planet that we know of that still make parts and rebuild these hard to find switches. These are the real McCoy round Delco Remy switches used throughout the Allis-Chalmers line of early Tractors using the 6V Positive Ground system with Generator.  We can rebuild your switch providing it's rebuildable) or you can exchange your rebuildable switch for one of our rebuilt switches. Your choice.  This is switch only. No rod and knob.
