Var1AbL3 sorry you had this issue, unfortunatly it's hit and miss on some of the link arm clamps and screws doing this. When installing new hardware just sneak up on tightening the bolt, you can actually get it to tight and the metal yields and doesn't clamp that well.
Alternative to these style clamps adopted from the Bally Williams days is to install my new keyed link arm clamps and shafts. They will be available mid to late December. You don't need to update or install them if your flippers are fine, but if they keep rotating due to the stock clamp then is will solve that problem.
