Disclaimer:
1) I used E233 Type Yokohama Line chassis instead of the recommended Diesel 10 or Boco Chassis (so don't yell at the guy who designed the shell) in the photos below. Hence the shell can't be strapped down properly. My Boco and Diesel 10 engines are stored somewhere deep in the storage locker. I don't have the time to look for them. So I used the chassis that is the most similar found in my house.
2) After you spray painted the shells, don't let any children to play with them as the paints are toxic.
