squareback alternator wiring in pre 70 car issue

It sounds like you are keeping the 69/ earlier regulator? I was hoping to keep my engine bay stock but with some stock upgrades. I'm assuming that I can't swap one without the other even if the replacement is the solid state/old style? I will do those tests in a little bit. I am not able to drive it in my area because 1) I'm right by an overzelous police dept and they ticket for any and everything, 2) it's not legal yet,3) I need to take my whole rear suspension apart to make it driveable. The modern VR I have is wider than the raised ribs the old VR mounts to. Thanks for the input
