The top was made by modifying the custom roof that comes in most of the AMT Shelby Cobra kits . Removed the rear section and then sheet plastic to build up the sides and roof . I have started making a new one that I hope will more closely match the one on the car . I used just the roof section of another roof but built the entire sides with sheet plastic and again made the roof a little longer . Needs to be puttied up and sanded still .
