IF you have ported vacuum, it would be a little brass tube on the engine side of the carburetor, at the base. If the carb is original, it may not have it.
While I'm all in favor of the new distributor (that's the path I took), have you considered just a simple tune up? IMHO, the first step would rule out the possibility of a bad condenser and/or points (for $30- $40) from a local parts store.
In your post, you mention a picture of the "points", but the picture is of the inside of the distributor cap. The points are actually under the cover plate below the rotor.
Your pictures looking down on the distributor reveal a condenser (cylindrical thing fastened to the side of the distributor, on the engine side of the terminal post) that is dirty enough to be original equipment. There's enough crud on that terminal post and wires that a thorough cleaning is in order.
A tune up is a one banana job FOR SOMEONE WHO HAS EXPERIENCE, but is likely challenging for a first-time mechanic.
