Addco rear bar set up. Uses 2 square u-bolts that you mount through the frame rail. Requires hole drilling. These mount the upper brackets for the links. I don't like the brackets to mount the bar to the housing but ours never moved in the 7 years this set up was on the kids Duster. Why a snubber? You're either racing or doing aggressive cornering. A snubber is generally set up close to the floor for racing but this is usually too close for street driving. Unless you have nice smooth streets your snubber will probably hit the floor. You can always lower it and raise it as needed.
