I am about to switch out my 130D 105 amp Alternator in my 2001 GP to the Delco CS-144 140 amp alternator-Many options at the link below all the way up to 250 amps and very reasonable for NEW, not rebuilt alternators. I also just switched out my 12 SI 100 amp alternator to a 140 amp CS-144 in another car from the folks below-really easy and they are very helpful!
