Alternator and Ignition help needed.

Working on a 66 Dart that has an original style alt with a field wire and hot wire. Its installed in the car with battery moved to truck and charging system is fine at 14.0-14.3. I bought a serpentine belt kit that included a one wire internal regulator alternator. (chrome plated) The directions say to remove the field wire and dont use it on the new alternator. If this is the case do I have to do anything with the regulator that is wired up or do i just terminate the field wire? I can get pics of new alt if needed and also copy of instructions can be posted.

As for ignition question, I am using a procomp box and distributor. Was wondering what I should gap spark plugs at. Should it be the old .032 -.035 or do I go to .045 or .060?
Thanks Rod
