I think if I am going to repair this, I have to cut the ball off and put something on the end to hold a new clevis. Unfortunately there's not a lot of room to do much.

Thought about cutting the ball off the pedal end and pulling the cable out but it's in the sheathing pretty good near the throttle lever end so there'd be no way to get a new clevis on. I'd probably destroy it trying to get it out of the sheath. Might be a lost cause.

Maybe this will help?
