I was doing a search & found this http://www.j-body.org/forums/read.php?f=4&i=156234&t=156234&p=1
Sadly that alt swap would only work on my 97 which I will be doing nevertheless, however I was unable to discover a similar alt upgrade for a 2.2 eco. So from what I gather the ad244 will work on a 2.2/2200 ohv but not the eco(unless it was shown to work) ergo does anyone know of a similar alt upgrade for an eco? I don't need it honestly, as my alt is fine and I have no audio system atm but the way I see it any modification helps.
I have a 220 amp alternator if you wanna buy it. used it when I had a lot of audio in the fire..
its practically new looking and the case has been blasted and built by a top end alternator shop.. mechman alternators
