IBM Card 1971 Duster 340

If you have looked at a IBM car with the option codes you will see there is no place for all the items on the Broadcast Sheet.

I have looked, and we are probably talking the same thing here, different language, or whatever it's called.
Broadcast sheet has more codes, however it all comes from the IBM card.
I like the details, and my understanding is the IBM card/data feeds everything to the broadcast sheet and fender tag.

The IBM card starts the process, and from that the Broadcast sheet is made for the assembly line workers, and the fender tag for them to put on the car.
The broadcast sheet gets tossed, put in the wrong car, or sent out the door with the fender tag.

The IBM card has all the data the broadcast sheet has, but it also includes the Region and Dealer Code, as well as the Shipped Date (the actual shipped date), not the same as the Shipping Order No., aka the Scheduled Production Date, that is on all 3, IBM/Broadcast/fender tag.

Everything on the IBM card from column 1-8, (skipping 9-15, Region/Dealer Code), 16-76, (skipping 77-80, actual shipped date) is placed on the broadcast sheet.

The last 2 sections on the bottom of the broadcast sheet, both labeled BUILD CODES, are for the grunts working the assembly line and tell them what parts to grab and put on the car.

Using a 67 383 A-body as an example:
DIST is the first section in the BUILD CODES section of the broadcast sheet, the part # for a 67 383 dizzy is 264224852, so 52 would be under DIST.
It's the only dizzy for a 67 383 A-body, auto or manual, therefore this code on the broadcast sheet is driven by the Engine Code on the IBM card.

Next is the SWAY BAR, same deal, part #24628389.
67 383 REAR SPRINGS, LEFT & RIGHT, 3 digits for each on the broadcast sheet, same springs, 2835056 is stamped on the springs, 056 is on the broadcast sheet for each.

My understanding is the 1/2/3 digit BUILD CODES are either stamped, on a tag, put on with a paint pen, or some other way.

I had saved an ancient article on the IBM process but I misplaced or lost it.
