Just so you at least get one answer, here is mine: I have no idea. If you have a local hobby shop you could go there and check out their bodies to see what might fit. However, from my experience, bodies are designed to fit the vehicle they are made for. As an example, the body for the losi xxxt will not fit the xxxnt, and will not fit the assoc t4 either. So all you can do is try a body by placing it over the vehicle and seeing how it fits. You can also contact hpi to see what they say. I hope this helps. I hate to see simple questions go unanswered because nobody knows an answer. By the way, is the rush an offroad truck or an oroad car? I have actually never seen one.
