I picked up my very first pin (#No Fear) recently and up closer inspection I see some damage apparently due to the (oversized?) washers on the sides of the playfield area. These don't look like they're the right washers. Can someone tell me a) what size washers this should have (if any) and b) if they should be flat or locking, and c) Is that clear plastic supposed to be removed or permanent? I know I could figure this out on my own, but I'm afraid I'll replace them all with my "best guess" only to find out I somehow made it worse. Thanks!
