I have an Excessive Amperage 250 amp alt for sale. Used for about 4-6 months but has been sitting for about a good 6 months now. It has been rebuilt and bench tested and does 250 amps ~ 1.5k rpm, at an idle it is about 100. It was built for a 96 Bonneville with a 3.8. I'm really not sure what other vehicles it will fit. I sold the car awhile ago and I'm only looking for $50 shipped to the lower 48.
