Put a 6v alternator on it (I put a one wire 6v alternator on my '38) and be done with it. Unless you're wanting to run a bazillion watt stereo you can put in a step-up (available on ebay for about $60) that will run most 12v accessories. I installed one on my '38 to run my GPS and it works great. If you choose to 'upgrade' to 12v my experience is that you don't need to put a reducer on the gas gauge. Years ago when I converted my 55.1 panel to 12v I never even thought about needing a reducer and put over 100K on the truck after the conversion without any problems with the gauges at all. It won't hurt to put one on if you're more comfortable with it that way but IMHO it's not necessary.
