Duster Space Saver Trunk Finish panel

whoot there it is... approx' 71 inches overall length and approx' 14 inches at tallest points.
Lower edge does have continuous flange facing inside. No part number found.
No cracks or damage over than the spot where a push pin goes near middle is hogged out a tad. They don't look exactly the same side by side.
I hosed the cobwebs off so water shows in the pic.
