David, when I sold my HUP, the fellow who bought it wanted it to be trouble free (12v) and had me do the conversion.

Don't fall into the trap of everyone telling you that the generator needs to be converted to 12v. It will work just fine as a 6v unit on 12v for many years as long as you don't crank it over for extended periods of time. 12v on a 6v starter should fire your vehicle in seconds.

As for the generator you can buy one out of the US that fits in place of the original one that is actually an alternator that uses the original style ford mounting and is a single wire hookup and internally regulated. A frined of mine has this setup on his 1937 coupe. As for a chev, one can easily mount a standard alternator with original bracketry from a 235cid motoras this is what I did on the HUP

All the bulbs is a simple one, just exchange for 12v.

Yes, the sending units on the fuel tanks present a problem as does the fact that your guages all run on 6v. You can either forget about using them, mount some postwar 12v ones in a discreet location or use a 6/12v stepdown unit.

There is no really simple way but all of my suggestions do work from my own experience.

There is another option, albeit more complex requiring a wiring diagram which I have also done before. This involves utilizing 2 x 6v batteries. The advantage of this setup is that you would run all your systems on 6v and use 2 x 6v in series for a 12v starting system after which time all is regular 6v. I would not neccessarily reccomend this unless you are quite adept with electricals as it can still provide you with the typical 6v headaches.

NOW, for my question...
Why would you really want to do a 12v conversion? The original 6v will work perfectly if you have met the following criteria;<<

-New, 6v battery, exercised on a regular basis and kept on a 1a trickle charger when not in use
-rebuilt generator, starter and new voltage regulator
- new wiring
- sqeeky clean and tight grounds
- new coil, plugs and sparkplug wires
-rebuilt and tuned carb and properly tuned engine
-rebuilt and properly timed distributor ( don't use the manual, you need a timing fixture)

hope this helps, Chris
