After searching for it a little bit I couldn’t find any spare wheels for your model.
If I understand you correctly, you are planning to replace all four wheels, so it would work if you get any wheels that have the same mountings and are about the same size as the old ones (just measure so they are big enough so the body isn’t laying on the ground and small enough to fit).
If you add pictures and measurements for the mounts and the size of the wheels, then someone may be able to found some that fit. [guide|21499]
