I have an 85 H40. I used to have spare time. The sheaves in the port and starboard deck organizers are jammed and cracked or broken. I've backed the 3 screws out of them but can't get the deck organizer off. The deck organizers are riveted together, so replacement is a given. How do I get them off without breaking the deck? There is no through bolt visible or accessible through the headliner. If they are just glued on how do I get them unglued? I love the boat. It's almost ready to sail. Just one more thing to fix...or maybe two more things...Help! I want to go sailing!
