Brake support #1404 983 needed for 11" brake shoes from a P27 (V8) or P26 (6cyl.) heavy duty # 1328-744. My topr shoe adjustment bolt is sheared off. My rig has to make it down an eight mile 7% grade this summer into Eagle, Alaska; no easy task with a two speed PF trans. Brakes need to be as perfect as I can make them. Anybody have a brake shoe centering tool I can rent? Please help.
