Quoted from cottonm4:I can see that/spacer/washer. in the bag. But the assemblies don't come with flippers or these spacers.
The flipper assemblies didn't originally come with the spacers from the factory, so we don't include them with the full assemblies we sell.
We do add them to the Classic Stern rebuild kits though.
Not everyone is going to want/need to use them, but they are there in case you do.
We also sell this spacer separately - https://www.pinballlife.com/nylon-flipper-shaft-spacer.html
