'71 Duster 340 Battery getting overcharged

Thanks again for the info. It appears I have one of the squareback/1 field alternators. I am posting pictures of what I have and I'll clean up the grounds and get the right square back 2 field alternator on Saturday...hoping the auto zone manager will help me out with the price. If he doesn't or one isn't available, what would you do with what I got? My green wire was not connected to anything as per the auto zone guru's advice...it was just hanging out there all lonely...what would be the impact of that? Basically one field is not showing up at the voltage regulator, but I don't know how that baby works...The two tied up rounded insulated connectors you see were from the original alternator decades ago...I've had this car awhile...don't even remember the change...but it must have been due to needing an alternator that had different connectors and not wanting cut off the original wire connectors.
