You can buy those panels new from a Ford dealer.
visit
www.tccoa.com and use the search feature in the forums sections. Pictures and part numbers have been posted there. They are not that expensive if you order from Max at 5-Star Ford, or Dan Newman at Joe Cooper Ford. You can also get ones from a junkyard.
EDIT:
Here's a link to the info.
