Hello! I am sorry to bother you as I am very happy to see that instructions are available. I am very confused over what one of the main pieces of the module is. The piece is the gear that rotates the GBC soccir and basketballs up the curves and out and on to the next GBC module? If you would happen to have a spare second, I would love to hear what the piece is as I wish to start construction of the module as soon as possible. Also, if you could include the piece number from Bricklink or Brickowl (LEGO part number), it would be very appreciated. Thank you!
