I agree that the carburetor is the place to look. Specifically, I'd check the automatic choke and make sure that the choke is opening after the car warms up. If not, the engine isn't getting enough air when its warmed up and that can cause the rough idle. You can easily check this by removing the air cleaner when the engine is idling rough and visually check to see if the choke butterfly is completely open (vertical).

Your carburetor is probably leaking fuel intermittently causing the idle to raise up and the car to shake will idling this won't be apparent at cruising speed cause the fuel is being drawn into the intake at a higher rate and the engine is burning the fuel much quicker. You likely need to re-build the carburetor and replace the float and needle and seat. These are internal carb parts & are what is causing your problems most likely. Depending what carb you have, 1bbl, 2bbl. or 4bbl could run you 75-150 to have re-built if you r&r yourself. Please don't exchange your carb unless yours is un-repairable 1963 parts are hard to come buy and keeping things original is always best for vintage auto's. If your handy and good at building small models or parts buy a carb-kit. Remember re-building a carb is really just a good cleaning and replacing the gaskets... best of luck.

the carb needs replaced or rebuilt but tune it up first with plugs, wires, points and condensor, rotor bug and new distriburator cap, a new fuel filter and then make sure you set the timing.

Have it tuned up, first. Then if it's still giving you problems, it could be in the carburetor.
