Anyone know off-hand what the sizes of the three factory Barlow (I believe)winches are on the O'Day 222 are? I am trying to track down replacement rings that top the factory drums. What I speak of retains line from walking off the top of the spool. They appear to be a hard synthetic of some sort. Once I have the sizes I intend to contact Hutton Arco to see if they have something that will suffice as a replacement.
