I guess I can add the tail end of the vin to make it more "original " looking.

Well - by way of clarification:

1 - No speculation here; I wrote a few of those notations myself.

2 - None of those are the VIN proper, or the sequential portion of the VIN.

Any serialized information would be the build sequence number. Nobody cares about the VIN in the assembly plant (other than to get the VIN tag on the right truck, just like an emissions label, SPID, or Mulroney window label).
