Maybe it was boxed wrong. Which one was off the car, and which one was out of which box. They both look very clean. I can take pix of my k783 and k781 lowers, and hold a tape measure up. Maybe what you have is for a 73 up disc brake car mis boxed. If both lowers are mis boxed and are XRF k783 and XRF k781 i would be interested in them. I am collecting up parts now for my sons 69 notchback. Its getting dippy discs. I need 73-76 A body lower ball joints.
