Due to mass production, I have heard several stories about any two unibody mopars not being exact. I have one that shows no sign of never being hit. When it was backhalfed, everything was measured off a factory produced location (trans cross member, leaf spring mounting location, etc.). However, the tire is farther inboard on one side than the other by a considerable margin (about an inch). I guess if all 4 wheels are square/straight and everything else measures correctly, it should be fine?

Good thread... thank you.
