1973 dart sport rear end offset

A 1/4" is pretty common, even a 1/2" difference from one side to the other isn't that unusual. More than that starts to be a problem. But it depends on where the difference actually is. Usually most of that difference is in the body, some of it is in the spring perches, etc. If it's been hit, you need to make sure the difference isn't in the frame rails.
