68 Barracuda Formula S 340 car Charging

Its a two wire..
One larger post and 2 smaller "field tabs".. I actually removed one of the tabs because I thought it may have been touching my valve cover.
The issue is that you have a two wire unit when the original was single wire. I understand the two wire unit can be converted, but I've never done it. I did find a reference to this here: https://www.justanswer.com/dodge/26xax-wire-charging-system-dodge-field-alternator.html
