I would say that if you are visually going to change your generator to an alternator, you should absolutely go with 12V

A 6V ALTERNATOR still won't run a radio, or a CB, or any other accessories. With 12V you can get a jump start from almost anyone, You can find batteries and bulbs all over the place. You can recharge your cellphone.

A 6V alternator looks like a 12V alternator, but by staying 6V all your saving is not having to change your 7 light bulbs and put a resister on the coil.

It's just my opinion, but I say you should go 12V if you are going to put an alternator on a restored Model A.

Things needed for 12V Alternator
- New light bulbs
- Chrysler ballast resister on the coil
- resister hidden in grill shell for the horn.
