They also stuffed them in the doors between the door panel and the weather proofing waxed paper; under the trunk on top of the gas tank, and up under the dash.
Remember there was more than one build sheet, each station had access to them as it rolled down the line and they removed them to verify the correct parts were installed and then discarded them wherever they would have to expend the least amount of work without littering their work station. There have been upwards of five build sheets found on a single vehicle; but it could contain none. Depends upon how lazy the worker was and strict his supervisor about trash as to were he stashed it.
Build sheets were an assembly tool to speed production while assuring accuracy; not documentation destined for authentication decades in the future.
