It's titled as a 1972 GMC K20. It has a Chevrolet front clip. The vin number I listed is on the glove box sticker that list the options, and the VIN listed is on the metal plate riveted to the drivers side door jamb. You say it doesn't look like a GMC VIN. What is an example of a 1970's era GMC VIN? I agree it looks like a Chevy VIN except for the "T" at the beginning. I can't figure out what the "T" means. I just assumed it is a GMC thing. Thanks for the help.
