Has anyone replace or repaired a Rutgerson Rope Clutch on a Hunter 28? I have a 1992 Hunter 28 and the main halyard clutch is slipping. I am waiting until the end of the year to take them apart! I have to following question. Can they be repair or do they need to be replaced? Are they a set of 3 or single units? Where can someone buy one? Thanks For all the help!!! Jim, DownTime
