Adding Speakers to the Duster Package Tray...

We have two cars with the speaker cutouts and the torsion bar lifts, so I know the speakers will fit in there.
I even removed some old 6x9's from the 72 Dart when I made the new tray.
Both cars had the factory cutouts in the metal under the tray.
I should also note that this Duster has the fold down rear seat option, as I know the bracing is different....
