According to Cowacarparts the box that they are selling is a reproduction of the original one. It seems that a mould has been taken from an original box and glass fibre reinforced resin has been used for the new one. There is no such structure on the original box that can be seen on the Cowacarparts box. This might be the reason, that Tomcatciller´s box is not straight.

Just by coincidence I stepped on Facebook into the manufacturer of the reproduced storage box that Cowa Car Parts is selling. A nice guy, who is also producing covers for the instrument cluster as replacement for the original ones, which are mostly broken. Unfortunately there are only RHD versions at the moment. But he is planning to produce LHD versions too. Also he is working on a storage box for HD vehicles.
