I'm looking at several 67 Chevelles. Could someone decode the bottom line please?

Nothing to decode, those are jut internal plants ID numbers and don't have anything to do with how the car was built. They used those numbers to process the car, had to have something to relate all the build operations to one central tracking number.

When that body came through the tunnel (from the Fisher Body plant )into the body bank, the clerk would use that number to ID the body, He entered it into the computer, which matched it to the order number and the VIN to start final assembly.

So the bottom line means nothing ? :(

Well, yes and no. They meant something during the assembly process to get the right parts on the car while making its trip down the assembly line. Unless you can find all the paperwork each employee used then no, the numbers don't mean much now. I suppose if one could get enough truly 'original' cars together (not restored or overrestored), compare every feature (is it automatic, does it have p/s, p/b, a/c, rear speakers, etc.) and compare numbers, you might be able to come to a reasonable conclusion to what tracking codes meant what.

Example, you are responsible for putting accessories on a base engine like p/s brackets, a/c brackets, etc. You're doing this well before the engine goes in the correct chassis. You put your p/s brackets and pump on, add your paperwork, and send the engine away. Down the line, someone pulls that paperwork, checks the tracking codes and matches it to a chassis, drops it in and gets ready for the next one. The final car's completion meant all these subassemblies had to know what to put on the line next to make a car at the end.

Think of the Assembly plant with a several lines probably a mile in total length but not in a straight line. For every place on this line, there is a feeder line suppling it with parts to build the car. Not all cars are built the same not are all cars on these line the same model. So the GMAD plants used a Data Processing Sequence Number for each car. Any and all unique parts or sub-assemblies a particular car required had to have a means to ID them so they were sequenced to arrive at each point on the final assembly line as the car did. They were building many cars per hour, 1 a minute was common and they just could not pile all the parts at one place, they needed to feed the line and in the proper sequence. These helped do that.

Once the car was released from the body bank to the assembly line, the computer system broadcast to all work stations that the car was coming and start the processes needed to make the parts meet it at the right place at the right time. The broadcast sheets (buildsheet) were printed out at each work station thruout the plant and given to the workers to compete their duties, then then would attach the sheet to assembly and placed in in the required sequence. Once the paperwork was printed, this number was not really sued anymore to any great extent. The broadcast sheet was the means to build the car.

If you ever get to tour an assembly plant, you will get a better understanding of what is involved.

Guess what year, make and model
