I found the regulator has a condenser wired to the regulator "A" terminal. Any idea what it is for? Cannot find it on the wiring diagram.
 
I have also seen them mounted on the back of the generator with the wire attached to Arm terminal. It's a good bet those old condensers are bad by now. Once upon a time, you used to be able to go to radio shack and get a noise interference capacitor and mount it next to your radio. It was about 1-1/4" diameter and about 2-1/2" long with a one-hole mounting clamp. Those were for use with solid-state radios (transistorized), not sure if they would be effective with the tube type radio's but I don't see why not. Don't know who might sell them now. Circuit city?
 
It was my understanding that when the voltage regulator cutout closed as the sydtem started charging the radio would make a loud click without the condenser.
I have seen cases where one was needed on the stop light switch too.
I had a customer with a 510 Datson that would make an annoying click sound on the radio every time the brake pedal was pushed.

Dave is correct. In fact, there's likely a noise suppressor at both the voltage regulator and the generator of that car (if they still had generators in '64.) My full size '61 Mercury has one at both locations.

I've also heard that they usually go bad with age, but I just got my Merc's original tube radio refurbished, and I was pleased to find out that both suppressors (which I believe are original) still work. No interference, anyway. Before I reinstalled the radio I looked for replacements though. I wasn't able to find exact replacements, but the guy who repaired my old radio seemed to think that some places still had new non-original units that would work. He referred me to NAPA. Some units had the same part # but different prefix, but that may have only been indicating a different connector. Or maybe not. Good luck.
