[COPO]

Sam, the bolt-on bars in the picture of my '67 BM Chevelle were actually installed later in its life. The original Motion Superbite bars were welded on the rear. The weld marks are still evident on the original rear end. I was lucky and scored an NOS set of the weld-on bars. The bolt on bars, however, were used by Motion on my 70 BM Chevelle.

Eric is right it will ride like a truck, but they sure look cool.
