Here's our theory: Wouldn't the VIN # have to come first? It was more than just a tag like the trim tag...it was stamped into the sheet metal itself (behind heater box on Novas & under cowl on Camaros). Fisher Body had to assemble the body before they could affix the trim tag. This explains why some cars with 6 cylinder VIN#s have V-8 trim tags, and vice versa.
