Did you buy a vehicle that had a title and you didn't check the VIN on the vehicle? To make sure they matched? Why? Anyway GMC did not do a good job at applying VIN to frames, only Chevy did a good job. Also as you probably know, Chevy VIN's are way different that GMC. Which style VIN does it have on the title? Chevy or GMC? As long as your state never inspects these years then it does not matter, build it like a Chevy, GMC or Hybrid. Obviously if you have already transferred title, they don't. If it has only one headlight per side, it could be some kind of crazy mixed up "fleet" truck.
