I'm so glad to move on. I'm happy with the outcome. I like the black painted backing strips. Remember that the window has thickness so you can see into the underlay. Having the black backing strips makes the view black and clean. Each side took 3 strips overlapping. 1 long one from roll bar back. 1 short one bridging to the 3rd long one.
Pilot side backing strip along inside edge. Black paint and 3 sections overlapping.
Window cleaned up nicely. All rivets are per Vans plans. No screws.
Co pilot backing strip. Underlap is 3/4 inch everywhere exc roll bar brace.
