I've seen these in Framingham Chevelles before, and almost every vehicle built at South Gate, CA. I never understood the reason for codes such as M21, when that piece of paper was usually deep inside the seat, before the upholsterer knew what kind of car it was destined for. I'd love to know who wrote these out, and at what step in the assembly process it was done at. </div></div>
Normally seats were built up in a remote area of the vehicle assembly plant (called the "Cushion Room"
due to fire concerns. Seat covers, foam and structure were all received independently from the various component suppliers.
The person building the seat up had to know specific RPO information (bucket vs bench, cloth/vinyl/color, seat structure - recline or not, power vs no power, etc) so that the seats could be conveyed to the main line in sequence order to be installed into the correct vehicle. This was the case for anyone building up or trimming out subassemblies that were conveyed in order: engine/trans, axles, front end sheet metal, the individual components that were built up into the bodies, tire/wheel assemblies, etc. They worked off the build sheet or build manifest to know what parts to install.
The information not only helped them while they were building it up but it also served as a double check for the operators down stream to make sure things were staying in line. If they happened to get out of sequence - that was a big deal, because it took time to determine how you got out of whack and what it would take to get back in order.

That's why their penmanship was always so bad!
