The high pitch stop is a bushing on the pitch change rod and its easy to get to without removing the prop. Normally they're set up to prevent the pitch change fork from bumping into the hub casting at coarse pitch, but there are also airframe considerations as is the case here. Its pretty easy to get to by removing the dome, but it requires a new dome oring and resealing the threads. The stop itself is just an aluminum bushing that one could easily duplicate on a lathe but longer to prevent the prop from interfering with the cowling.
