Ok Guys I would like to take four inches out of my 27 Roadster windshield stanchions and maintain to top where to top is held. I think if I cut the stanchion just below the top windshield pivot then 4" down from that point then weld the bottom part to the bottom of the top pivot it should match up pretty close. This is my first time doing this so I need some expert advice. Thanks Jim T.
Here is one I did. glass is frameless, sits in channels attached to the posts. posts were chopped like you asked. https://www.jalopyjournal.com/forum/threads/picture-test-touring-windscreen.39585/
