The frame rails on my son's 1968 Dart 270 are different. From the wheelwell lip to the frame rails outter wall the right side is about 7/16 shorter. The tire will rub on the right but not on the left. I thought I had messed up so I got under with a plumb bob and sharpie and made all sorts of marks on my concrete floor. My spring boxes are welded in the right place on the frame rails but not in the centerline of the whole body. It is still 7/16 inch offset. FUBAR! I ASSuME'd the factory was close....
