i made a steel windshield frame with two steel protrusions at the bottom, intended to go through holes in the fiberglass body.
where the "forks" come close to the body, I glassed a metal piece of angle steel on each side, which i have drilled one hole each.
Here i will bolt the windshield frame to the fiberglass body, much as i suspect regular cars are assembled.
yeah, I'm gonna have a glass shop use two component glue to hold the windshield to the frame.
