The front section of the roof is curved. In order to bend the panel to follow the curve of the side panels we made cuts every 15mm on the inside of the panel.
It took 8 people to put the roof panels in place and glue them onto the side panels. The red tape is holding the panels in place until the glue cures. The lower end of the panel is clamped to the chassis.
The roof consist of 3 sections which are joined with alu T-sections from above and glassed over inside. This was the easiest way to fit the roof and it still took some effort to complete. No way I could have done that at home.
