Fitted and cut the windscreen. The main windscreen bow had already been placed. This was not complicated except that while tapping the solid bow I BROKE A TAP DEEP INTO THE BOW! What an absolute pain in the neck.
Others have noted that they needed to make a long reach tool to reach the nuts for the firewall to windscreen joint. I made that same tool but discovered that my wifes acrobatic reach was perfect. She was able to hold a wrench to all of them.
I placed a VISTA VENT into the pilot side windscreen. This made me nervous as I used a (brand new) hole saw to make the major cut. Worked out fine.
