The mod was made from one stock windscreen. Unlike most forum members, I find the screen too tall although I am 6 feet tall. In the heat of summer I like to have a breeze to cool me down (the one disadvantage of wearing a full protective suit ). I cut the screen down about 4" on a scroll saw, then changed the shape of the top piece slightly before taping it to the lower half so that I could mark it where the holes and slots should go. No, I do not have templates, I just winged it. It turned out that the slots did not hold up too well and cracked, so I got another screen from someone on this forum and re-did it without the slots. Once I found the best position, I never changed it anyway. I now iether use the combined shield, or if it's particularly hot, I remove the top part and put it under the seat. No, I never did try to make the whole screen adjusable. Probably not impossible, just too much work for little return! Sorry I can't help you any more.
