This feature is quite cool, although I fear that I am missing parts. In a ziplock bag I received one of the smaller sidewalls of the holster labelled with a number 1, but they didn't include another of the same sized sidewall for the other side of the holster. Is this normal? Also, I received two larger sidewalls labelled number 4. But unfortunately both of these sidewalls are facing the same direction so I can't hook them up at the same time. Is this normal? I am left with the option of connecting one of the smaller sidewalls labelled 1 and one of the sidewalls labelled 4, which makes the phone a bit crooked on the lightning connector. Let me know what you received with your car and if I should call Tesla for more parts.
