Alternator wiring 66 Dodge Dart

Would like to add that I was going to change to electronic voltage regulator from mechanical regulator so I would like to know if I should upgrade the green wire from the alternator field to the voltage regulator and also would it be a good idea to upgrade from the blue wire coming out of the voltage regulator going to the firewall plug and inside the car. Also was going to go from the alternator to the starter relay with an 8awg fuse link wire. Hope I'm not confusing the hell out of you but I probably am...lol. I would also like to thank you for sending me the wire schematics 67dart273.
