Hi everyone, I just bought an old O'Brien Freesail board (I'm not sure if the "Blue Thunder" part is important, but I think it's awesome!)

It has everything, but the mast connection is broken. I believe it's the U-Joint that snapped off. It's the piece that comes out of what I think is the mast track and attaches to the mast. Can you guys let me know how to fix that piece?

Any help is greatly appreciated!
