69 Dart GTS 383 4 Speed Completely Original
For reference, below is the original type belongs on your car at right. You can barely make out the grounded brush at about 5 o'clock or so. The insulated brush is at about 7-8 o'clock
On the left is a mid to late 70's so called squareback. These are a better design. You can use them in your car in two ways. First, just ground either brush (field). Otherwise, use the 70 / later regulator and add one more wire to the harness

Below is one of my favorite things to ***** about. This is a 69 / earlier alternator which some cheap a$$ rebuilder has drilled an extra hole to mount a second, isolated brush so they can sell it as a 70 / later alternator. PROBLEM. You can accidently get these with both grounded and isolated brush installed, causing a short, they don't use factory brushes, and generally, "not the way" things are done

Below we have a 70 - 73? alternator known as a "roundback" It works the same as the "squareback" pictured earlier. It has TWO isolated field connections. You can use either this type or the squareback on your car with the original type regulator, by grounding either field, and hooking the rest up
I say "73?" because I'm not sure when Ma switched over from round to square back. 73, 74, all models may not have been changed at once, and might have depended on the factory
