Yes, thank you for that info Ed that is what is on this boat. That was why I was scratching my head because there are no other blocks on the stern of the boat and I could not see how all of the cam cleats would work together.
I appreciate all the help with this folks, it is starting to come together and if my sure-to-be-spectacular-looking rudder casting repair job goes as planned, we will hopefully be on the water by Sunday.
