Lonnie,
Then you might consider mounting it on the bottom of the diff.....the way it was set up from the factory. Still pointing the bar ends to the FRONT. I'm assuming that you have the tank mounted aft of the diff.
My motive for mounting it on top, with a stock suspension height, was so I wouldn't have to scrounge up longer bolts for the control links. IMHO I think bottom mounts would accommodate your 4" suspension drop. Hope this helps.
