If I remember correctly on the installation guide, you have to take the OEM corner brackets off the soft top and then install them on the back mesh window for it to work.
Nice! Let me know what you think. We haven't installed ours yet but probably will tomorrow. Just a note on the back window you have to use the OEM corner pieces to install it. Kind of a bummer but the price is so good. I'll probably end up just using the side ones.
