The date on the fender tags and broadcast sheets is the SPD / Scheduled Production Date.

Many online decoders call it the 'build date' but the SPD was assigned when the order for the car was first entered into the system as a 'target' or 'hopeful' date.

Quite a few cars with early in the month SPDs have mylar door stickers showing they were complete in the earlier month, so it would be cool to know which month yours shows just for fun.

This also happens with cars with later in the month SPD dates that were completed in the following month.

Many factors could affect actual build production and real world 'build dates' were not recorded until later on.

Cool to see a Duster with 3 on the tree too! :)
True, but the day the vehicle was entered into the system is the day it became a real production product. It was the very first step in the process.

We could debate all day what “build date” means...first two parts put together, last parts attached, factory completion, delivery sign off, etc. etc.

The point is, once it was initiated in the production system, that vehicle’s production was begun as specified and it was on its way to become the vehicle that was delivered. Before that, it didn’t exist.

I’d call that a “birth date”.

Happy Birthday Duster!
