SS/B and SS/A Chassis and Suspension

After reading an article in MotorTrend July ´68, on Landy´s Dart, he ran 10.5 X15 on 6 X 15 wheels, I´m a bit puzzled here. But you can´t be sure an article is 100 % correct I guess, and of cause they may have done some testing with different size wheels.

On first photo Jilly has to have more than 1.25" positive offset, that came original with steel wheels. And car still have tires well in line with the body, which is very obvious on black and white photo. Could it be she ran an A/body 8 ¾ rear end. It was available for the ´73 modell A-Body in summer/fall of ´72. Other vise I cant see how 10" wheels fit so well... with original rear axle and springs not moved in further.
Photo must be ´72 as she become Miss Mighty Mopar in ´73, and also ran other brand wheels then.
Don´t laugh, I need help here… :) But will not take this any further now...
