72 Duster here. Stock spring location. 8.25 out of 75 Dart. 15x8 Wheel Vintiques ralleys. 4.5 BS. 275/60s. Tires are very close to the springs and rub during sharp turns. A 4.25 BS would probably be ideal for my car but i don't think that offset is available in a 15x8 ralley. Did you bolt the wheels and tires on the car or did the customer take them home and put them on himself?
