http://www.youtube.com/watch?feature...WeijmfOA#t=33s Seems to me from the video and from other research I've done the only difference is the diameter of the case (other than the internal parts) the mount holes are spaced exactly the same. Presumably the only issue would be clearance with the engine or other parts. In any case like he showed in the video the diameter change is minimal a quarter of an inch at most. And the width of them doesn't look to be different. The voltage regulators are universally mounted between 6g alts just need one that works with my car. Gotta go to the wreckers tomorrow for some axle shafts I'll grab one while I'm there. Another guy on the forums put one of these on his 2.3l so it can't be that much of a hassle.
