Need part number for ordering

I purchased a Aqubot Turbo T Product # RB-AQA-73 in 2010 from the Robot Shop. It has been in for service twice since I purchased It, once under warrantee. There is a white thin plastic piece about 2 1/2 inches wide that extends on the inside of each track from the front brush to the rear brush. What is the correct part number for the right and left side for this piece. Thanks.

Hi Brian, can you please send a picture of the parts you wish to order to our support center?
We’ll then verify if it’s possible to do a special order for these.
