depends on which body you have (manufacturer), but I guess it could be the German fiberglass body from H. Uhl????
Your question was:
Chassis: MOMO sidewinder or inliner
Motor: Plafit Bison
Wheels: Sakatsu with Wiesel tires
anything realy: decals to be looked at ; I have no idea myself, maybe you try Fred Caddy or DMC or Caligraph
Hope that helps. Maybe you can post a photo of the body!!
