I'm just putting the last finishing touches on the interior of my super original C-10. Today I attempted to install a reproduction cardboard fuel tank cover that fits behind the seat. I must be retarded or something, because it just didn't go well at all. Seems like there needs to be some additional pressed-in creases for folding in key places to get a nice fit. I have never seen an original cover intact before, or a properly fit repro either, so I don't know what they are supposed to look like, or exactly how they fit. I know this detail is one that most truck owners just don't bother with, but I'm going all original. Anybody put one in successfully? Got tips? Or does anybody out there have a picture of an original tank cover in place?
