Will the alternator from a 96 4.3 fit in a 93? I know they have different cases. Are the mounting points and wiring different?

The '96 has a Delco CS-130D small case and the other one probably has a CS-130 with an external fan.

There are some good close up pictures on http://www.alternatorparts.com

I just got my 170 amp alt for my '97 from these guys about a month ago.
