Both my 71 car (with an assembly date code tag of 0780), and Bill Meerholz's one owner 70 AAR (assembly date code tag 0580), have allen hex adjusters on the steering gear. The parts catalog shows different screws for 70 (slotted screw) and 71 (allen hex screw). Based on that, I would think that the overwhelming majority of 70 non-Fast Ratio cars would have the slotted screw.
