Fiberglass hood, stock hinges

I have a race weight glass hood for my 65 valiant I've been sitting on for a while and would like to install now. I don't like the ideal of a lift-off so would like to glass in some mount points for the stock hinges. I will still likely pin it at 4 corners but would like the convenience of being able to lift and prop it. The torsion springs have been removed so the hinges aren't under any tension.
I've never worked with glass before but my first thought is to glass in some angled aluminum brackets in the same location as the factory mount points on the underside. Has anybody else ever done something similar or have any other ideas?
Thanks!
