Re: Symmetric Rudder damage and surprise hardware!
Is it possible that the bolts are also part of the rudder shaft attachment to the rudder skins? I would make sure the shaft is still tight and refill the the depressions with thickened epoxy and an over lapping layer of light glass cloth. then go sailing for another 10 years. it does look like the way it was made by Clark and would have been filled originally with polyester filler back in the 80's
