Be sure to have the roll bar in place before you drill any holes.

I would not simple use the screws to form the bezels. That puts them under constant pressure; like being spring loaded. I wouldn't want that constant stress through the fiberglass.

I have a large round metal pole in my basement, that holds up the center beam. I press against that to bend them into the shape I wanted. A little trial and error, but no big deal.
