So I got the truck home. Was a little more rough than I was hoping but it was cheap and worth the spare parts. Box is still pretty decent and will look much better on my truck and the engine runs really well.
I did find some cool stuff in the glovebox though. Some original purchase documents including the original owner who bought it with 23 miles, it's first oil change at 1800 miles, and a diesel supplement.
Another cool thing I found also is that it was bought new at the exact same dealership in Lincoln, NE at the exact same time as my 82. It was also built the same month as mine in April 1982. I was hoping they were built close to each other but my 82 was built in Janesville and this 2WD was built in St Louis, still pretty cool either way.
