So I'm watching a YouTube video from some guy I have not seen before, his channel is called Junkyard Digs. He's working on a Mustang II and he's talking about alternator upgrades. He explains a little about 1g, 2g, 3g, etc., and says there's tons of information on the web, and shows his computer screen. What do I see but Gary's own forum!
Here's a link to the video. He made out like a bandit on that particular project purchase, I'd have to say.
