'68 Barracuda top with glass window

The OEM hard back glass will have a Corning logo on it. It's large and shaped much like a notchback glass. As far as I know, that correct glass isn't available new. A new aftermarket top with a hard glass will include a flat, generic glass.

And that is the bummer about losing my original one. It was blown out by the guy that did the sandblasting on the undercarriage of my car.
