Jazzman, while I am working on some ideas, can you take some measurements of your rear deck? Tell me the depth at the edge and also let me know if there is anything obstructing access to the rear deck from underneath? I don't have a contour any longer so I can;t check on my own. Be exact as possible when describing what is there. A drawing would be even better.
Aaron, if you or anyone else has quick access to their car, or a good memory, let me know if you can help.
