In the vein of the mileage statement I'd like to point out the aptness of one of the stated features of the truck. The "duel gas tanks"!
Yup,them old "Binders" were never known for their mileage, they were made as work trucks and boy, howdie, they sure were good at it. I might have missed it and it may not matter to you but was it a manual (most likely being 4 wheel drive and a '67)?
Needs "interior"? What, another coat of house paint on the metal panels? I don't remember a whole lot of "interior" on any of the IH's I drove. Throw on another horse blanket to cover the springs when the old blanket wore thin was all the interior we needed. Tape another piece of plexi-glass over the wing window when the old one got scratched to opaqueness, ever' now and then get a different board to hold up the window when the old one warped.
