Do you have a shop nearby that can get hpi product? If so you may try to get some cyber10b parts. The arms, cvds, hubs, etc will fit. The upgrade slipper is for the cyber10b is the same as the d4 wce (Not sure on the center cvds thought).
You could probably post a WTB thread for parts here. Or even post on Petit RC. I cannot read french, but I look at the pictures over there.
