CA Light Switch and Resistor

I'm trying to locate a couple of parts for my light//hi-lo charge switch located in the instrument box on my 1952 CA. There is a small resistor on the light switch and the nut and bolt hold for the light switch rod, also need the knob, but I'm pretty sure I can get that from Tony & Barb. I would replace the whole assembly, but its $75. The one I have is in great shape. Any Ideas? Still 6 volt system.
the function of the light switch is to turn on the lights, ground the F wire from the generator when the lights are on, and ground the F wire thru the resistor to ground when the lights are off. you can do that with a double pole, double throw toggle switch and a 3 ohm resistor if you dont want original.
Thanks Steve, I will splice-in a 3ohm resistor. Still need to get the nut and special bolt assembly that secures the original push/pull switch to the ignition box.
You can get the high/low charge light switch from The Brillman Company for $45.00. John also has a really nice free catalog for tractor electrical.
