what can I use the v8 alternator out of just jeeps or can it be any 5.2 or 5.9 like a pickup

 

Here is the list I found a while back

97-98 Dodge B Series Van
97-98 Dodge Dakota
98 Dodge Durango
97-98 Dodge Ram
97-98 Jeep Grand Cherokee

Edit: I am not sure exactly what it is called but the plastic piece on the back of the Alternator that your + Cable goes to might need to be changed, just undo either the stud or the nut and the black plastic piece pulls off.
