I used a 1 wire 10si before in my old race car, in my opinion,, its just not worth it for dependability/easy to fix if rosadside issues. I never had a problem with mine, but the thought was always in my head. They way to go is the stock system or a regular 10si GM alt in my opinion. I also agree with an above post, the chrysler alternators look sooo much better cleaned and painted up.
