I'm looking for a couple of turning blocks that mount on the side of the cockpit that turn the traveler line 90 degrees to get to the cam cleat at the top of the cockpit rim. The deck plan diagram lists this part as "block, bullet lead, upright, p&s". The boat is a 1992 CP-22. Catalina Direct doesn't have the item. Harken doesn't have a replacement. Does anyone know where I can get these or a substitute?
