The Roadmaster # RM-1139-145 is the correct rear anti-sway bar, and the steering stabilizer fit is the Roadmaster Exact Center Steering Stabilizer # RM63RR.

The SumoSprings you're looking for are # SSF-171-40-2 for the front and the # SSR-184-40-1 for the rear. These are all confirmed fits for your F-53 Chassis with a GVWR of 20,500 lbs.
