Bolt fix will work, just make sure you have lock washers good and tight. I did that to a Card Whiz 6 years ago and never been a problem. When i got the game, the flange was off and loose in the bottom of the game. All the reset arms (you know those male parts) were gouged so bad, they all had to be replaced from PBR. While you're in there, check the axle, nylon bushing (if it has them), rubber reset bumpers, etc. for wear. Clean all the old grease off and start with just a drop of super lube at the pivot points. Targets likely need a cleaning also. Ah-oh, now you enter the can of worms scenario.......
