I was going to try to keep the original wiring harness, and with it the original style alternator. Its the Chrysler style (not sure which amp, I assume 90). Its too big to fit in the original style 440 bracket. The manual says it is regulated by the SMEC (computer?). If this is the case, couldn't I swap in an earlier style alt? I was concerned about not having an external voltage reg, but it sounds like the alt I have now doesn't have one either. Any comments or experience on this? Thanks, James

They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
