You can use resistors for some things but those are a bit problematic if you don't have a good idea of current required. Too little current thru the high wattage resistors usually sold for motors doesn't drop voltage much and too much will still burn the resistor up. Proper size resistors have been used on instruments as have other methods. If the car has been converted to 12v negative ground, there are Runtz modules which will work a single gauge but gets expensive if more than one is needed.

If 12v bulbs can't be found or adapted for the fog lights then those, the gas gauge, the clock, heater etc would benefit from a 12v to 6v reducer. but in using a converter or reducer the wiring would have to be separated so the intended items get the correct voltage.
