I have a 66 Dart with 15x10" wheels. I think the wheel wells are the same. I moved the springs in 3" and did a mini tub to make room for them. Im not sure you can use a 10" wide without moving the springs and tubbing. Have you actually taken a wheel off and measured for proper back spacing? I highly recommend doing that. By the way, my backspacing is 7.5". If I were to do it over again I would cut the rear housing down at least 2" per side.
Best of luck

that is just what I was thinking I would have to do. I was just hoping to save some money on cutting down the axle. Looks like it might not be as easy as i wanted. I am already planning on moving my springs and mini tubing the car.
