Recently bought an HJ45 advertised as a 1978. Got the title in the mail and the title reads 1980. I can't find a data plate on the doors, door jambs, or firewall. My VIN ends in 037427 (title and frame stamp match), and every thing on this truck seems to indicate 197X vs 198X. I can't seem to find a chart showing production dates for non-US trucks. Before I go to register and title this in my name, I'd like to make sure I know the right year. If it is a 78 (vs 80) should I try to have the title updated? Thoughts?
