First figure out your pattern and drill the windscreen with either 11 or 13 holes. It has to be an odd number. First start at each end and one in the middle then space the remaining.

Then do the same with the screen on the car in the position you like. Take your time. I think it took me a wlhole day to get the results I wanted. Then use stainless slotted screw with those special stainless neoprene backed washers so you don't screw metal to plexi.

Start in the middle and work you way out to the ends. Make sure the holes are a bit larger than the screws so not to have any bind since they might be at an angle before being completely tight. Go slow. You will get it.
