Removed at 20k miles. Very difficult to tell this from a new one, as can be seen by the condiiton of the chrome, the push-rod and other fasteners. In excellent condition, esthetically and mechanically, and is pop 'n drop: Lever, push rod, pivot bush and pivot pin are lubed. The dust boot was dry, I removed it to prevent the temptation of using it. This deserves a new $12 boot.
