66 Valiant Electrical Issue?
You can run the old style alternator, but I wish I'd been able to forewarn you. What you SHOULD have done is buy a later model "squareback" (isolated field) and just externally ground one of the field terminals, and you could then later convert to a 70/ later regulator if desired
MOST replacement 69/ earlier regulators ARE actually solid state. Turn the regulator over, or just look "back there" with a mirror. If there is two large resistors on the bottom, it's the old mechanical style If not it's solid state "in the old box"
Old style mechanical design:
You can also buy a better quality 69/ earlier design which actually will work on either late or early models
Standard no VR-128. I forget the NAPA / Echlin no. offhand
