The front section of the wheelhouse was cut out and the three windows marked out and cut out. Then two lengths of angled aluminium were placed upright on the front and held in place with 3M clear tape. This was to give the correct angle for the front window section. The section was taped in place and then liquid plastic glue applied along the joint. Aftfer the glue had set the side windows sections were measured top and bottom to get the correct angles. Once cut out a little filing was needed to ensure a good fit. Then the windows were cut out and the side sections glued in place.
