I remember reading an article about a rebuild kit you could get for a GM alternator that converted it to a high output setup. The kit included new bearings and and a rear case, as well as the upgraded internals to handle the new current output. I think the kits were around $150?? The only problem is that I can't remember where I read it. I know it was in one of the major 4x mags but I can't find all my back issues. Has anyone got any idea who sells these kits and if they're any good?? Thanks!
