That will severely effect the handling of the coach, resulting in a terrible pull to the left. I would correct before I drove it anywhere. You could put all the aluminum ones on one six pack and all the brass on the other. You are lucky you have six of each.
This happens because the brass and aluminum have vastly different magnetic resonance properties, and as you know the coils just above the body are electromagnets when energized. The imbalance in magnetic fields has been shown to cause animals including humans to become disoriented and lose their ability to move in a straight line.


Preposterously joking of course.
