That looks very similiar to my truck when I bought. My guess is it was restored by the same guy that did my 77 and not the guy that owns it now. There are a number of things that are painted and detailed exactly the same way my 77 was.
I'm a little puzzled about the mileage claim though. I do know that the guy that restores them sometimes changes the gauge cluster. Maybe the current owner truly thinks the miles are correct.
Regardless it is a very nice truck, and if it was restored by the guy that did mine, the work is top notch.....
