Give Rudy a call
I think that Rudy Nickerson of D&R Marine may be able to assist you on the hatch. Rudy has parts for O'Days. If it's a forward hatch, he will probably be able to match your boat with a hatch that will fit. The company that made a lot of these hatches for the later model O'Days, no longer has this particular hatch available. If it's the companionway hatch, he may be able to help you. I'm giving you a link to his site. Give him a call on the phone. I don't think he answers his email. Good luck!Joe
