This is kind of what I was thinking. I don't care about period correct. The car already isn't period correct. I just care about reliability.
I have a couple old alternators I stripped from some late chevy 6s that should probably do the job. I'm hoping they are internally regulated so I can just do the one wire thing.
I'm just going to have to get the resistors for the gauges/blower motor, and some new light bulbs it sounds like.
This is encouraging to hear. Investment should be low. I will keep everybody updated. Thanks.
