Any chance the 902 number refers to the PVI number or vehicle order number, instead of the GA number? From your last post it sounds like the GA number isn't known until the assembly process. In the research I have done, that number shows up before the assembly process. I have documented that number showing up during the stamping of the pieces used to make the truck. Here is a example.
I took this pic and the stamped number is 214
I have documented several trucks with the stamped number matching the grease pencil number. Any light you can shed on this would be greatly appreciated. I have used the info you provide in your posts a lot to help me do this research. you are a most valued resource. Thank you for all the knowledge you share with this board. We need more assy line guys on here.
P.S. I love the story of how you followed your truck down the line. To cool
