What amp is the alternator?
I did find a photo of a 67 Barracuda 383, voltage regulator on firewall. Mine did not have one there, or to the best of memory and photos, anywhere. Unless what I thought was a starter solenoid is actually the VR. It is not marked in any useful manner, and it is located toward the front of the engine (near battery tray - see photo - you will need to expand it). No VR on firewall prior to the ballast resistor, and the only possible VR is that cryptic box on the inner fender, with lots of wires (including a heavy red one) connected to it that does not look anything like the VR's I see online and at parts stores.
