Rear Axle Identification

E-bodies are the only car rears with the dimensions you mentioned. I don't know anything about the seller or company that sold you the lines but almost all of us here have had mis-packaged parts one time or another.

Could it possibly be a truck rear? I don't have any truck rear specs. A truck rear would have the perch on top of the axle though so it would be quite noticable.
