1965 dart rear wheel question

I have the chance to buy a centerline drag pack in 5x4 pattern for a decent price, but I wanted to make sure they fit before I pull the trigger, does anyone know if a 8.5 inch wide rear will fit on a 1965 dodge dart without cutting the wheel wells or moving the springs? As far as I can tell the offset on the centerline is around 4.5 inches or so.
