What is the intended function of the aluminum piece that gets mounted in the center of the lower windshield surround? It's listed in the manual as "rear hood support aluminum". If this is its intended function then It seems to me that I would want to install this after the hood is fully mounted and in its proper location. If it was a bit wider I could use it to cover the master cylinder cut out. As it is this only covers about half of the cutout. What has been your experience?
