I haven't found the build sheet for my 86' Regal yet and I have had the complete interior out so I think the only place left for it to be is on top of the gas tank as far as known hiding places.
I wasn't really concerned where the Regal was built it's finding that 30+ year old build sheet that is the fun part.If you enter the VIN on the link I put at the beginning of this thread, it'll tell you where it was built.
