68 Dart wiring questions

We are working on my uncles 68 Dart. For now just trying to get it running and moving before we worry about what’s ‘correct’.

My first question is can I use an alternator with 2 (I assume) field terminals when his car only has wiring for one (green.) I have that alternator and we are hoping to have a charging system while we try to keep the motor running long enough to tune on it a bit.

See this post, but I think it will stick better if you read from the top post.

Begin with a charged battery and make sure there isn't any high charging or discharging of the battery.
Monitor the ammeter when the car is running.
Someone here in recent memory fired up a new engine with a battery that needed charging.
The alternator worked great, so provided over 40 amps during the break-in. The owner saw the high charging on the ammeter but didn't understand the importance. After 20 minutes all the connections were melted. :(
