you need a Cup alternator, you'll also need a pas connecting pipe making up. I got a local fabricator to use a baided steel line on mine by cutting up the existing item, copper braised (sp?) it and it's good to go. Think there's something else you need, possibly the PAS return line from the Cup as well, canne remember.
I'm actually putting mine back in though, f**k weight, I'll just buy more power lol
