Look into a Powermaster alternator avail from any on line or local speed shop. The one wire jobs can be also wired as a conventional 3 wire and that eliminates having to rev the engine to get it started charging when the engine is first fired up. A minor thing but a lot of people find it more convenient to have it charging right off the bat at idle. As far as neatness of the wiring re: one wire versus the 3 wire set up, some people can still make a mess out of just running a single wire so it really is not a big deal on a car that is a driver if you work neatly.
Happy to be of some help,
Mike
