Charging issues on a ‘64 Valiant...

If you want direct drop-in electronic, this dude is your best pick.
Actually Dan, that one has also become hit or miss in terms of survival. I e-mailed Standard's tech and asked how much field current it could handle. The tech couldn't find out. You can see where I'm going. I suspect that regulator can't handle the current draw of some of the 'higher output' alternators, in particular probably most any revised squareback. My backup now is FBO's version but can't say it will be more durable or not. Just what I will try next. And it looks original for those who want that.
