Here's some pix of how it works. I've no interest in marketing these, but happy for others to replicate the idea on non commercial basis. The rear screen just clips in top and bottom. Plastic must be acrylic or it will yellow in the sun. 4mm thick, you can bend the curves over an
oil drum with a hair dryer. Just make sure it fits in the boot. Rear vision is wide screen and super clear too. Good sun protection in summer with screens out. Works well.
