If you are pulling the mast base off anyway you might as well go with the new style rotation system.

I had one with a broken pin hole like yours. I stepped it that way for a couple of years before I finally sold it. I always tied a safety line to the dolphin striker and I had someone pull the mast base toward the ball as I stepped the mast.

Or just replace it. Anybody know if it's glued in or not? If it's glued in you might have a problem replacing it easily.
