steering column wire terminal ??

what are the round column connectors called ? are they molex connectors ? and there are two sizes used. a large one for the start, run, accessory plug and a smaller one that is used for the turn signal switch. what size are they ? car in question is a '72 duster. i'm guessing these were used on many years and models. lastly, where is a good place to get these ? TIA.

The .093 pins are the small ones, .125 for the large pins. I got mine and the tool from the above link.
