Yeah that's what I assume has occurred. If you look at the ball trail on the third photo it leads right up to the screw, so I assume a kickout back up that lane will have the ball hitting that post/screw every time. It should have been riveted on the other side.
In order to fix that I assume I have to drill the rivet off? Any suggestions on what sort of rivets to buy to refix it. I also need to rivet a few of the new plastics too.
