[70 c30 longhorn]

Hey everybody, I have a 1970 chevy c30 longhorn. The front independent suspension is wider than the straight axle in the back. I want to lower the whole truck but the front wheels are so far out that they would rub the fenders if I did. All of the wheels are the same size. I want the front wheels to be aligned with the rear wheels. Drum brakes all around. Any suggestions/solutions?
