Anyone know of a clever person who made a Filler Panel from another car fit onto a Galaxie?? Convertible just to make life more interesting...

This panel goes from the base of the rear window/canvas back to the trunk opening. I suspect a re-pro for a (hate to say it - Chevelle) could be modified to fit. Better to work with new metal rather than semi rusty panel, if I can find one.
