That tube (or steel rod, basically) that your brake and clutch arms pivot on is one tough piece of metal...incredibly tougher than the bushings, so it isn't likely to have worn out.
Agree, but if you get enough grit in there, they will wear some. My original had some definitely visible wear on it, so I swapped it for another one off a later frame I had that had some very slight wear marks. I just put in the pedal bushings that were advertised as undersized to compensate for worn shafts, but they were a good fit on the shaft that had maybe 2-3 thousandths wear (I didn't measure it.)
My pedals had worn the upper part of the holes where they go thru the firewall, but then my front cab mounts were basically non-existent. The arc-shaped pedal arms can only go on the straight arms with the bushings, because they have grooves in the mating parts where they bolt together.
