I've been looking into this truck, but there are a few flags that I'm seeing based on the pictures he's sent. Looks like the bumper and grill surround are probably from a 70 or earlier truck as the turn signals are strapped behind the newer style grille. In the larger res pics the emblems are readable as Cheyenne 20 Super (which obviously wasn't from a shortbox). The cab does appear to be a 72 as the rearview mirror is mounted to the windshield at least. All in all it appears to have been patched together a bit by someone. That doesn't necessarily bother me as much as the possibility of it having been shortened. I'm still waiting for pics of the SPID sticker and VIN tag, but thought I'd post on here and see if anyone happens to have any first-hand knowledge of this particular truck.
