If your going to do things like listed below you are going to have a much longer list and have to identify (like in some other areas) which plant. Not sure if you have identified exactly the range of the points you wish to cover IMHO.
Tags -paper-
Axle
Distributor
Things that could fall under the same heading above - engine ID tag, Dearborn inspection stickers, wire loom labels, assembly line stickers (that would have been removed during dealer prep, and others. Maybe breaking out the paper label products would be better in a separate thread. Just a thought
Also
VIN stampins-
Engine
Transmission
Aprons
Maybe under a different individual thread also?
