[oletrucks] What kind of alternator should I be looking for?

["Scott Tyson" <scott-tyson@worldnet.att.net>]

I want to convert to 12v on my '51. My question is what type of alternator
should I be looking for. I don't intend to run any serious electrical stuff so
output isn't an issue. I know the older ones used external voltage regulators,
newer ones used an internal and the much newer ones only use 1 wire. The later
type seem to be all serpentine belt pulleys. Any suggestions?
