alternator wiring conversion

hey everyone,
what do i need to do to convert my 64 darts wiring to run a later-model one wire alternator (square back)??? right now i'm using the original 40 amp /6 alternator on my transplanted 360 and i really need more juice. does the amp gauge need to be eliminated in favor of a voltmeter instead?
finally, is there a place to find wiring diagrams that i can print out?
thanks in advance!
