questions not so clear. But if u mean can the skyline bodies fit on teh rsx chassis or vise versa i dont think it can. They are as durable as u drive it. Flip and crash it alot adn it wont be very durable will it ?
Because the RSX chassis has a short wheelbase, the only body which will fit is the RSX. However, you can get a long driveshaft and extend your chassis to the long setting. Then you just need another body and the front mounting tab from the corresponding car.
