Calvert makes a kit that fits inside the Mopar inboard spring kit boxes. (Where you notch out the rear frame and weld in the boxes). On my duster I used this kit with tubs and was able to fit the M/T 12.2 radial on the car. It did however take substantial trimming at the front and back of the wheel well. If I recall correctly I used 10x12 wheels with 7" back spacing.
