I have hull # 329, 1980.  Great boat.  Noteworthy tasks include new sails, replacement of stuffing box, remove of vinyl (foam backing) basket weave wallpaper in cabin and the addition of tabbing on one side of a starboard.  The other side was already tabbed.  I think bulkhead s should be tabbed on each side.
I sail Lake Michigan out of Chicago, Monroe Harbor.  I have owned the boat since 2004.
