The front end looks like a couple of trucks I've had. A 1970 and a 1971. The very early Dodges had 4 had 4 headlights. In 1965, Dodge went with 2 headlights in the middles of the year. They had large trim rings around the headlights. I think you have a 1968-71 model. I don't have the numbers off hand but I'll look around to see what year it is if I can find my old books from the salvage yard I used to run. Here's a better photo of your data plate to make looking it up easier.
