I converted to the GM 12SI 96amp altnernator. This is a 3 wire so the dash light still works. You'll need to remove the voltage reglator and connect some of the wires together, correctly of course, and add in a diod. One wire needs to be moved to the starter solenoid for voltage reference. But in the end it works great. Jon Haas, Pantera Electronics, is very helpful. I actually bought a replacement GM winring pigtail at my local auto parts store and replacement crimp connectors that fit in it. Installed them on my factory wiring for what now looks like a factory install. Very clean!

Diod identified by the black Sharpie line on the spade connector.
Yellow wire moved to the battery side of the starter solenoid for voltage reference.
This is before I found the factory pigtail.
