Oooorrrrrrr...... If by chance you're open to building your Chevy in junkyard or ghetto style, you could just use the broken one and add some more cracks, perhaps a bullet hole.
i did this to my Fw190 canopy after failed attempts to remove paint overspray. I saved a broken Jeep windshield in a similar manner. Granted, these are military combat vehicles, much more likely to be sporting bullet holes than your Bel Air. Just thought I'd share the option with you.
