The following diagram shows all the bushings for the clutch/brake linkage. It's pretty straight forward rebuild;

I would tighten that clutch linkage up 56'. It will give you headaches in adjustment if the components are worn. Replace or repair anything that will cause you lost motion.
Like gm said, the rubber pads showed up on the pedals later. They were bare steel in the old ones.
