Wheel/tire combo for '73 Dodge Dart sport

Put 15 x 7 (4¼" BS) Magnum 500s on the /6 mordor. Tires are 205/60-15s. No problems with clearance. This car has disks which widens out the front track about 1½". Car rode & drove nice. You didn't say if your car had drum brakes (SBP) or disk brakes (LBP). Makes a huge difference in terms of wheel selection.
