I've got a CS144 alternator kicking around that I have no use for (hunted it down for a swap, only to find out that the guy whose posts I was reading for instructions was doing it on a V6, and not applicable to a V8. He has detailed the swap here.

I was looking at getting $40 plus shipping (because this pig is HEAVY!) It's not filthy, but it's not clean either. And it tests as working fine at the Checker and the Autozone.
