I have to replace the package tray in my 71 fastback. Some catalogues(not all) also show a separate item for a layer of insulation. My car doesn't have this insulation under the package tray(missing?). Should there be? Also, any suggestions as to who has the most correct package tray(material) for sale? My interior is black, and most catalogues say to paint. Larry's Thunderbird & Mustang Parts http://www.larrystbird.com) says theirs comes in black.

Thanks, Jay
