I bought a big case GM alternator, fits a lot of 5.7 liter V8s and 4.3 liter V6s, and the 3800 series V6s.. I need to make it fit either a supercharged 3800 motor, or a 3100 motor in a lumina. Anyone know where i can turn for one of these? I don't know anyone that crafty local, and traveling with the car is a possibility
