5) Shelby has a tonneau cover, I'd be cautious about sourcing it from anywhere else due to the differences in body shape. I also believe Shelby has a template for the snaps. Mine fit like a glove.

I'd second Mark IV's comment to be sure that the proper backing material is present. If you can't find out from DenBeste how the car was built I can get you a contact at Shelby American that can probably look up the build sheet.
