Hey Will G, cool truck!
You will have to do some investigating to determine the year without a data plate. I found out a lot of information on my red '42 with a 27 year old Montana license plate.
I was able to trace it from Montana, to South Dakota, Nebraska, and eventually Iowa which is where I bought it. I even talked to the person that owned and licensed it 27 years ago. The Montana DMV was able to send me a photo copy of the title when it was licensed in 1980. I think the search cost me about 25 dollars.
Be safe, I hope you get home soon.
John
