You've already got a non-adjustable panhard bar, so yes, the bracket should hopefully be there haha. Depending on how far you're planning on lowering it, you'll want to look at an adjustable panhard bar. I'd say 1 1/2" drop or more and you'll need the adjustable in order to re-center the rear portion of the body over to axle.
