Mike,
You've really only got two choices. Twist the spindle until it bends. Otherwise drill a small air bleed hole through the butterfly of the one with the lesser airflow. In reality there are usually three throughts to adjust the airflow on though so drilling the holes is the only way to do it correctly.
