Beneteau 311 Waupoos
Greetings! Most of the white plastic caps covering the nuts and bolt tips coming through the headliner for the hardware mounted on the cabin top have broken. They fit 1/2 inch nuts (o/s dimension) and are 1/2 in height/depth. We sail our Beneteau 311 out of Waupoos Marina in Prince Edward County, Ontario. Marine Outfitters in Kingston and West Marine don't seem to have anything suitable. Any suggestions for where I might find these beauties would be much appreciated.
Happy Sailing!
