Bill,
If you installed a single wire alternator, all you would have to do is connect its BATT output to the wire that attached to the 12 volt BATT terminal on your old, firewall mounted voltage regulator. It doesn't get much simpler than that.
There are probably belt width/pulley issues too, but they are pretty self evident. Good news you didn't freeze to death in Tempe...I'm drowning in rain in Eureka.
