I'm no electrical expert but have gleaned this from a friend who is.

You can change all your bulbs to 12 volt. Nothing else needed there. You will need to add a coil resistor to the coil for it to operate properly. The starter will operate OK on 12 volts. You’ll have to use 2 step down resistors in parallel for the heater and for the instruments you’ll want to use a Radio Shack heavy duty DC Auto voltage adapter. part number 2731815. Set the slide switch to 6 volts, cut the wires off and wire the input to your ignition switch and the output to your instruments. Add 1 step down resistor for the radio and you should be all set.

CENTERLINE is correct. And thanks for that part no. I usually get a Volt-a-Drop unit from good old J C Whitney to do the job. The wiring in a six volt system is heavier than a twelve volt system and (if in good shape) works well. I usually just install a 12 volt battery, ground the negative side, then replace all the bulbs that blow out. Volt-a-Drop covers the instruments and motors. A chrysler ign resister for the coil. Then use a one wire GM. alternator to charge the system.
