Does anyone know the dimension of the (larger) pictured rubber? It’s not on the schematic (see picture) - the 7/16” rubber labelled ‘G’ is the small rubber on the little post at the top.
I think the rubber currently in place is too large, and it keeps periodically deflecting the ball into the centre of the playfield during plunge.
