Steve, If you don't want to drill, the Ronstan RF5110 clam cleats have the same hole pattern as my originals (and probably yours). My were worn out, so I recently replaced both jib sheet cleats and the CB pennant cleat.

I'm thinking that if I'm going to replace these cleats, maybe I should replace them with cam cleats instead of the clams that are there now -- my experience is that cams tend to hold more decisively, with no slipping. Does anyone have any wisdom that would contraindicate the use of cam cleats for the jib sheets? -- Steve McClellan M15 #152 Chicago Area _______________________________________________ http://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats
