You are allowed to use CIM motors from previous years. The banebots gearbox from the 2007 KOP however is not legal. Those were made specifically for the KOP and are no longer available as a COTS item. These gearboxes had a flaw in the carrier plate and are no longer manufactured. However, banebots does sell an improved model with identical mounting holes and output shaft that is legal here:
