Maybe I've misunderstood some of what I've read but it sounds as though the core support stampings looked funny to the O.P. because the characters weren't lined up evenly. My experience with old Mopars is that this is not unusual and is not necessarily a sign of tampering. He didn't say that those numbers didn't match the VIN. Although parts were put together from 2 separate vehicles I'm not sure this car would qualify as a re-body. - More like a car that's gotten donor parts from another.
