if yu r welding the xmember in the z uni isn't needed, but the higher uni in the column is the same size/spline as the rack

I just have to strip the donor to get it moved before the neighbors start complaining don't you know. once I get it all out I can finish the cab floors so I can pull the cab to work the frame. I took the whole steering column so I have both ends for now.
