If that ever happened to me, That is how i was thinking of getting the centerboard back up.
Here is a couple of pictures of my Pendant. It's nothing more than two bronze straps, pins and a swag connection. I have every reason to believe that is the original set up, but not sure.
While you have it up on slings, look at the roller up in the trunk and see if it rotates. If it doesn't it might have a groove cut in it by the pendent cable. Also look to see if the cable has a groove worn into the fiberglass in the hole at the top of the trunk. If it does, let me know and I have an easy fix for you.
