Anyone know if you can run a 6V heater blower mtr. on 12Volts without any problems. Thats the only thing left on the 52 that was 6volt. I ran it through the orginal switch on the "bench test" & it did cut the speed on LO but don't know if switch will handle it for any length of time ?????

I wouldn't worry about the switch at high speed, as at high speed it's providing a short (zero ohms resistance). I'd be more concerned about the low speed on the switch (as the resistor is now handling twice the voltange, and hence twice the power) and also the fan motor.
Sending the full 12 VDC (or more likely 13.5 Volts) to a motor designed for 6 VDC sounds like a formula for increased heat in the motor.
Or just run it, they will run at a higher speed that they are designed but will usally last becuase the 6 bolt units have heavier windings, you can get universal heater switches at an auto parts store and just use that to turn down the speed. but they arent built to a very high quality and those dont last, even on a regular 12 volt system, blowe motors pull so much current they tend to burn out switches, that why they usually have blower relays on em nowadays. you could figure out how to wire in a gm blower relay and switch from a 70's era and that would probably work fine.

Was hoping to run the original switch to keep dash "sorta' stock even though the cluster is custom. As long as it will work for when safety is done,then it can "burn out"

This voltage reducer allows the use of an original 6 volt heater blower and switch in a vehicle converted to 12 volts. Safer and much more reliable than the less expensive ceramic type voltage reducers. Compact 1" x 1" x 3" size occupies little space. Reducer works with up to 10 amps of continuous current draw.
Note: This reducer generates a fair amount of heat when in use. It should be mounted to a non-flammable object, preferrably near cool moving air while the vehicle is in operation.
OK, I checked a little more - I know that the Painless Wiring brand (first one I showed) is pricey, and shipping from Speedway is pricey, so I checked my closest parts store (Advance in USA) and they had this:
