Alternate package tray materials for '68 notch back Barracuda

Hi all,
I have not yet removed the package tray from my '68 notch back Barracuda. It is faded and I am considering options for replacement. I am not sure I want to replace it with a stock type or make my own out of a hard board material.
With other model Mopars using a metal package tray, has anyone ever fabricated one out of metal for this model year?
Thanks in advance.
