A photo of the aluminum sticker in the cockpit by the hiking strap should have the correct number for the sail and numbers at right starboard rear .... Last two should have age
No rush for photo but saves me a trip.
It was easy....just do the proper measurement...If old just buy some new parts....from APS or Intensity...its worth it ! Nice fit later....Line up what you think is original hole...See that from the top of mast present. Then use a string to get proper line up at the new bottom. Use SS rivets...
