Canadian GMC SPID

[davem815]

I have a few question about things on my SPID that I have not seen before. Maybe these are all Canadian plant differences
1. Vin number appears to have been printed at two different times. The model info is lighter, and the serial number at the end is darker and different alignment. Like the SPID was removed from the printer, then reinserted to be finish printed
2. The W/base contain IN. What does IN mean? It is a 127” long bed.
3. SE number. I have read it was common for the Ontario plant for include a SE number
4. The color code and interior trim code are listed at the top of the SPID. I have only seen them listed at the end. Was this a Canadian way of doing it?
5. The color code is mis-aligned.
6. There is a blank line in the SPID. I have never seen this before
7. No emission option code, but the engine has an air injection pump. Truck is a 1970 C2500. I thought 3/4 tons were exempt. I would not expect emissions equipment on a '70 unless it had a SPID option listed.
Are these all just plant variations?

I can not upload pics. I tried from desktop and mobile. I have never had a problem before. I will try to add them later.
