Is there a specific 12-volt generator that will drop in without much trouble? It's on a 216 babbit-pounder with 5/8 pulley. Also, same question about regulator: Is there an easy replacement? Thanks.

I believe that it is from a 55 Chevy sedan but the main thing is it appears to have very similar dimensions. The regulator looks almost identical. | | | | | Joined: Feb 2007 Posts: 385 Wrench Fetcher | | Wrench Fetcher Joined: Feb 2007 Posts: 385 | Consider a 'single wire' 12 volt alternator unless you are trying to maintain originality. You're going to have to change the same parts for the switch to 12 volts, but I think that the alternator will be better in the long run.

Most of the 12 volt units ran the narrow belt, but it's a quick switch to install the wide-belt pulley off the 6V generator. Of course, you'll need the corresponding 12V regulator to work with the generator. That's a straight-across swap also, using the same wires.
