Tom,
Great info on the build sheets. I have not found mine yet on my CS (have not started the tear-down of the interior), but I have found it on my convertible. Like hcsstang stated, mine was very brittle, especially the part that was on the outside. It was folded into a size about 1" x 2" and taped to the dash wiring harness. I very carfully unfolded it and only lost the part that stuck to the tape which was at the point of being absorbed by the glue from it. Like Tom stated, other than the VIN #, DSO, color, engine size and trans mission #, everything else is jsut a number or letter, ie shocks "1". It does however give me an idea of what may have been an option on the car (the Marti Report does this better) if you look at it and there is a number/letter in a certain area. But not all are indicated.
I hope when I tear my CS apart I will find one in the seats or under the carpet, both are still original!
Doug
