'96 has the following:
Gen 1 engine
Gen 2 exhaust (hence the 415 HP rating instead of the 400 HP for all previous Gen 1s)
Gen 1 body (doors, hood, no windows, no external door handles, etc)
Gen 2 suspension
first year to have wheels other than the three spokes.
and other minor things, e.g. only year to have stock sliding windows (all previous years were zip-up vinyl), etc.
