I recommend upgrading to the later model charging system. I did that to my 67 cuda.... one wire solid state to two wire electronic regulator with 75 amps. Also did madelectrical.com amp gauge bypass. I installed a voltage meter later on. Ran a 4ga wire from the alternator to the starter solenoid. My headlights was brighter is one thing that I was after and they don't dim at red lights any longer. You can get everything you need at the local parts houses.
