Z4 E85 rear windscreen brackets

I wanted a new design for my 2008 Z4, So the side mount is curved to fit (flip to fit other side), All pcs are held in place with clear silicone and its made for 1/4" Lexan or polycarbonate or equivalent. Its the first version so it could change, lol
UPDATE: I plan on using 3/16 or 5mm so it isn't so tight!
