I can understand how the windshield will push the cowling out and to the curvature of the windshield although, I have my doubts that it will be enough. The top cowling is pretty rigid and I can push it out at the center/top and it does pull the sides in a little. If I push on the top cowling to mimic the pressure the windshield should put on it...I had to push pretty hard to insert this piece of wood and the results are pictured below. It comes in a little, but not very much and definitely not completely. There has to be some amount force applied directly to the side/corner. My thought is making a metal lip welded onto the front door post in order to capture the top cowling and pull it into and snug with the door post?
