Looking for a wire form I believe. At the top of the shooter lane and entering the E-A-T lanes is the solid gate. An inch below that it appears on our game a missing wireworm to prevent the ball coming down the dinetime lane as the solid metal that would hold it is there. As it is now after he ball ejects from the skill shot, it immediately heads for the flippers. A mangled wireworm was found in the cabinet.
If it is a wireworm any idea which one? I see a couple of candidates 12-6902 or 12-6904 but nothing comes up on Marco.

Thanks so much! I was going to ask for a pic and you read my mind!

Thanks so much, this drawing is confusing, and that part number you referenced is above it (on the play field) and is a switch wire form. They are above one another in this 2D drawing. I think its actually part (21 a) in your picture. Because of your post and picture of the parts list, well, there it is! https://www.marcospecialties.com/control/keywordsearch?SEARCH_STRING=12-6565
