Anyone know the part number or similar replacement part for the 1-way ball gate assembly flap, just the flap, the bracket is fine but the flap is rusted and I would like to replace. The manual has the part as B-10732-L (#23 on page 62) which is discontinued from what I can find but it is the whole assembly.

Anyone seen this or have suggestions on how to 'fix'

When the ball is shot from Dracula's catapult and arrives at the left inlane it come in so fast that it bounces from the in line to the outlane and drains. Doesn't happen all the time but enough. Can the power of the catapult coil be reduced? Or other suggestions?

Thanks
