COPO disassembly

Thanks for the info Greg, very informative. The Fisher Body/Chevrolet sheet distinction makes it all much clearer to me now. But a Fisher Body sheet won't tell you anything about engine and chassis components correct...just a body or job# and a interior trim style. It's the Chevrolet sheet that is integral in confirming or disconfirming a car's drivetrain components then. The only build sheet I've been lucky enough to personally discover, was a full Chevrolet sheet w/ all option codes spray glued to the backside of a Baltimore built '70 SS396 Chevelle door panel. The only rub was that it was on a used door panel I picked up at a swap meet and the car was long gone. I would imagine Fisher sheets are much more common to find as they would most likely be the ones left inside a vehicle and away from the elements? Does anyone know if it is common to find a build sheet glued to the backside of a door panel like this on Baltimore built Chevelles?
