I went ahead and purchased the rubber dash tray liner kit. In it you get 3 parts: one ea for the storage areas to the left and right of the steering column, and one for the glove box area. The instructions that come with the kit, confidently indicate (in 4 languages) that if you are fortunate enough to have the glove box option, you may trim the large liner at the points marked on the back, so that it will fit in the glove box.
Can't for the life of me find those trim markings on the back. Can anyone else who bought this kit help?
