Today I continued to finish the holes I previously cut in the windscreen. The first step was to finish opening up the second hole to very close the the correct size. I also filed down some of the molding flashing on one of the snap vents to get the best possible fit. I expect to open the holes a bit more after fitting the windshield as I expect the curve of the windshield to distort the holes.
Before installing the windshield I realized that I needed to cover the curved areas of the firewall just above the glare shield in order to prevent glare. I used a piece of file folder to make the pattern.
