1966 Barracuda "car ****"

I think you might be able to upgrade to a dual master cylinder and keep the same booster and vacuum tank. A friend of mine was in AZ the last couple of weeks and found the tank but not the booster. He wants to add the correct PB set-up to his 65 Valiant. I recommended using a 67-72 booster and eliminate the tank but he wants it to look correct. Should you want to ever sell the booster (or both), let me know and I'll put you in touch with him - he's another member as well.
