It's a fairly simple conversion but have you considered the simplicity of putting a 6v alternator on your car to address the higher amperage draw of your lights? That's what I did on my 38. There are also 6 to 12 volt step-ups that you can install that will allow you to run your modern accessories. I have no experience with Vintage Auto Garage so I'm no help there. I've never converted to electronic ignition so can't help you al lot there. One point to consider, be aware that you'll have to change the coil which means you'll have to do away with the stock electrolock and maybe even install a modern ignition switch.

Before going through the time and expense of the conversion what are the reasons you want to switch?  If you are not adding any new electronics that will draw power then the existing 6v system should handle your power needs.  If it is hard to start check all of your grounds etc.  Converting to 12v will mask ground issues for the time.  Pertronix makes allot of conversion kits for points to electronic ignition if you want to go down that path.  For my 41 I have found NAPA still caries the ignition parts and coils.  If I wanted to convert I would need to wait for delivery of the part if there was an issue.  The original ignition parts are cheep enough to have a second set on hand.  

If you are looking for faster starting remember that faster cranking does not equal faster starting.  12v systems do crank the engine over faster but do not necessarily cause faster start times.  With my car I have found one of the biggest variables was the time since the car was last driven.  If I see fuel in the glass filter I know it will fire quicker than if it has to pull it all the way from the tank.  

I did have a generator go and replaced it with a rebuilt generator.  If I had to do it again I would probably use a 6 volt alternator.  That would give me more amps in the future.  

I have a lot of accessory lights(fender lights, fog lights and one s-1 spotlight plus my column fan and a rubber bladed fan as well as want to install a modern sound system. I think I will slowly go toward modernizing the drivetrain while leaving the original esthetics. Thanks for the tips gents, does cause me to think in more detail. 

Here's a web page on 1937 electrical. . home.znet.com/r1937/12Volt.htm . An electronic ignition will keep your car in tune longer than points BUT I bought Rotor, points, condenser, and cap off the shelf at O'Reilly's last week. If you modify to electronic ignition, you'll have to call a tow truck and find someone to figure out what you did. Tho 1937 standard generator had a cut out, 1938 passenger cars came with a voltage regulator. A newer 6 volt generator would power extra accessories if you couldn't find an original 1938 option. One of my 37 Chevys has the original 6 volt alternator. A 12 volt alternator was also an option for 1937. (See web page previously mentioned.) It is possible to get a "Booster" that will provide 12 volts from a 6 volt system for your boom box. Good luck!

A 6v alternator can easily handle your electrics. I put a 60 amp on my 38. The downside is that it ruined my stock ammeter. The stock ammeter is made for the OEM generator with a max in the neighborhood of 30 amps. After a couple of hard starts where the alternator was slamming 60 amps through it to recharge the battery, it gave up the ghost. I ended up putting a 6v voltmeter under the dash and bought an NOS ammeter in case I ever want to go back to the stock generator. I believe 40 amp alternators are available which I'd recommend you use if you go this route. A 40 amp should easily handle all your needs.
