Early Dodges had passenger drop and drivers side disco on the tube. Most likely, he has one of those, and is looking at it upside down. Makes it HP drivers drop huh? If it's cheap, grab it and rape the kuckles and brakes off of it. They are flat tops and 5x5.5 pattern. Way better option then going with a Chevy/Ford combination to get 5x5.5 and flat tops. At least all your parts come from the same application, makes buying bearings, pads, etc easier.
