and we should look at the regulator and regulator wiring.
If you can make a larger or sideways photo of the wiring diagram, we can be sure its not different than '62
According to the Tech booklets, the alternator wiring looks the same.

The regulator adjustment is a little different. So if you have the original 1960 regulator, the shop manual and is booklet are the ones to follow.
In 1961 the regulator adjustment changed a little.
Another difference we see in the illustration on that page

Iit looks like some (all?) 1960 models still used a starter with a seperate solenoid. You shop manual will clarify that. And we can also see what is on the car.
That broken yellow wire looks like it may have been an attempt to wire in a starter that uses an internal solenoid. With more photos of the starter we can figure it out.
