You need plexiglas, 4 mm thick, four times part 1 and two times part 2. If your windscreen is not long enough and you need two parts, then you need additional part 3 and part 4 one time. ------------------------------------------------------------------------------------------------------------------------ It was very stormy.

"********************************************************************************" I have construct a new version. For this version you need a plexiglas , 2 mm thick, for the rear side and 4 mm thick for the side parts. A 2mm thick plexiglas is strong enough if it consists of one part.
