WTB: WCS Plastic

I just got my WCS and it looks and plays great. I do need one piece of plastic for it. Mine is broken and it causes the ball to hop out of play. The piece I need is the one shown in the attachment. All I can find this in are full replacement sets. I don't need that much since mine are in such great shape.

Thanks!
