Steering stabilizer

What is your question?

My truck did not come with a steering stabilizer I am looking at putting one on and looking at the bilstein. They have one that is supposed to be a direct fit. Just wondering if the holes/brackets to attach to are already there or if I need to get additional hardware? The truck has 130000 miles on it, I am replacing the shocks, and I to a heavy 5th wheel camper frequently.
