Voltage regulator location? Need a new alternator?

Should be externally regulated.
Regulator should be on fire wall.

It's a 67 Dart 270 but at some point a 318 was swapped in. When I traced the line it didn't seem to run into anything before getting wrapped in with all the other wires. I can go take another look though.
