RE: Does this precut prepainted body fit ?
It's a question of wheelbase and track width, especially if its precut. Look at the wheelbase and track width of the vehicle it's intended for, then look at the same on the vehicle you want to fit it to. If they are the same or very close, you should be fine. If the wheelarches are precut, you want the wheelbase to be literally identical in order not to look weird.
Which body is it (model)?
