My first suspect would be the voltage regulator. In the '60s and early '70s, these were external to the alternator, usually mounted on the back side of the radiator support. The most common failure point was a thin wire inside the regulator that would melt when the system was overloaded. You can check the basic workings by removing the cover from the regulator and looking for the remains of the missing connection. While you're in there, you can also check to see that the 'points' aren't damaged or welded together.

Other possibilities are corroded battery terminals, loose wiring connections, dirty or loose ground connections, etc.

I'm not sure if it will help, but here's a nice diagram and explanation of how the charging system works in GM cars from the '60s:

would this help with my problem? im assuming the regulator has never been changed but im not sure
Id throw a voltage tester across the battery teminals while its running and see if the alternator is putting out @14.4 volts. If not pull the alternator and have it checked before you start tearing into other things.

If you are reading 14 volts while running, it is charging. A battery normally sits at 12.6 volts so anything above that is the alt doing work. Why do you say it is not charging?
