Hi Rich, Pace did fit a rocker for the rear brake to the original new for '92 RC200 frameset. You should be able to work out if it was the same as the RC35 fork as that fitted to a spigot on the bridge using a circlip. Do you have anything welded to the frame for it to fit to or is it just a screw hole on the rear mono stay, that would suggest a std type rocker anyway hope this gets you thinking Cheers Max. Ha Ha to slow in my reply you have posted pictures
