RC51 caliper mounted on Super Hawk lower fork tube. The caliper needed a bit of grinding on the lower mount to fit. It wasnt too bad, I just had to sneak up on it, both on the caliper and the fork leg. On the fork leg I basically ground of the casting draft to flush. - I had to be careful, if I overdid it, I would have two pieces of junk, or maybe a good boat anchor.
