Centerboard circle above pivot

hi:
On my centerboard the cable is broken. It looks like the cable attach somehow on the inside of the centerboard. tried uploading some photos to no avail.
Anyone know how to fix this centerboard cables
Me going to pry or drill out the filler in the perfect circle just below the cables and see if there is a holder of some kind there.
