How to Disassemble the Car
John Griffin provides the following tip: the roof of a heavyweight is held on by tabs that are visible by flipping the car over. If you are going to paint the car, be sure to take the roof off, as the windows are part of the roof. This eliminates a lot of masking.
These cars consist of an injection molding of two main parts. The roof includes the window glazing that fits down into the sides. The ends and floor is the other part that also offers the underbody details. The trucks are added.
