What direction did you rotate the back-plate, CW or CCW? When hold my lens with the aperture "L" facing me, a CW rotation of the plate would locate both the adjusting knobs on one side and the locking knobs on the other side. I have read that modifying the 24mm PC requires a ribbon change. Did you have to make any ribbon modifications?
