RE: I want to build an RC 1948-1952 chevy truck.
Proline makes a nice 5 window 50 chevy pick up. It is made for the Stampede or Rustler, but you could make a nice little scaler of about 1/12th scale out of it. I put it on my old Rustler and it looks pretty good. I would include a photo but I just signed up and I'm not sure how yet.
