Am converting to 12V with a two wire alternator (GM 10S1 series) that has a built in solid state voltage regulator; does this mean I would not have to use the regular firewall mounted external voltage regulator? Do the 12V headlight switches have a relay built into them? Where would be a good place to mount a horn relay on a '36?

Bob, you will not have to use the firewall mounted regulator. The 12 volt headlamp switch does not need a relay unless you are using halogen bulbs or sealed beams in the headlamps.I'm not a big fan of halogen bulbs. Good reflectors with 12 volt bulbs will give you plenty of light. If you need a relay for the horns you can mount it in the engine compartment. Use an existing hole in the frame to mount it. Just for information if your car has the stock light switch at the bottom of the column you can use this switch with 12 volts.

We leave the regulator in place for appearance, and use just the battery terminal as a junction point for the alternator output to feed the system. Be sure that the wire that turns the unit on is connected to a point that is "hot" only when the ignition system is turned on, not an accessory position. Doubling the voltage of your car drops the current (amps) to half of the original 6 volt demand, so the wire size should be adequate without a relay for the headlights unless, as Tom points out, you are going to halogens or other high demand parts.
