Truck cab question

I've owned 3 trucks of that era/body style. No military trucks, but I don't believe you will find any diffences between the two, but never say never. What you got now fits for sure.
You don't know what you got till it's stripped and if it has a hole in it there's likely to be more. How bad is yours? Everything you get is going to need some body work. Being the nut I am, I'd go look at it, but that's not saying much. It ain't that far of a drive.
