Q. At this point, I'm not concerned with getting all the guages; limited as they are; just the simple "Idiot Lights"; What exactly do I need to change when going from the 6 Volt to 12 Volt?

It has the following:
12 Volt Battery
12 Coil (Internal Ballast)
Correct (appears) Selenoid
One Wire Alternator.

If all those components are working properly, the "One Wire Alternator", simple connection, "one wire to Positive Battery terminal";

Q. Would that be sufficient to charge the battery?

She starts right up; the horn works, the gas gauge works; lights go on, turn signals work; NO CHARGE?

Read step # 13 in the link I posted above.
