I do agree totally that the cross ram is impressive. I just do not see why someone would pay two arms and half a leg for a GM setup that is not original. Now if the person buying believed that it was original equipment, I could see where they would be convinced that they need the GM setup. And perhaps, that is who is paying these prices. There is certainly a lot of info along with people out there who are at least implying that these were original equipment, dealer installed, etc.
