I went yesterday and bought 24’ of 3/4” thin wall square tube. First I need to get the frame built then I can decide if I want to attach it to the door or raise it up hinged at the top and locked at the bottom.( Lambo style ) If I attach it to the door I can probably cover it with the soft windows I already have with the zippers. I also can cover with lexan and that’s probably the way it’s gonna happen. I remember reading a thread where a guy had the flip out windows fit I can’t find it. Hopefully he reads this and posts the link I would like to look at them closer. I will share results but it’s probably not going to happen soon no time for projects this weekend.
