I'm about to go the other way, mountig a 24v alt for my winch batteries.

I already have a second 12v holden alt mounted where the a/c compressor was.
I just put a double pully on it to match the a/c belt alignment

cheers smitty

Grab a falcon or commodore 85A bosch alternator, $40 or so at pick-a-part. If you can fab up a bracket and mount it on the engine somewhere and get a belt on it so it turns, I would say we can talk you through the wiring side of it pretty easily.

This might help:
