Need some electrical help with my ‘68 Plymouth Valiant 100

Red arrow points to a special clip that makes a positive ground for the voltage regulator to the car body

Glad to hear the engine compartment is looking good to you, that gives me some encouragement that it wasn’t a super rough one to start with.

Anyway, I am sorry for how clueless I am, but just to clarify I will need to purchase specifically an “electric” electro mechanical regulator, but NOT a regular electric one?
