So, if I understand you correctly, you are saying that there is a neutral safety switch currently located on the steering column, when there was a standard console shift, and this sounds incorrect to you?
I have a '70 floor shift automatic, all original, and the neutral safety switch IS located at the base of the steering column, down by the floorboard at the 12 o'clock position. I would expect the same to be true for the '69. So, if I have interpreted you correctly, I would assume the steering column is original (or at least same as original). The switch is mechanically actuated by a linkage from the console shifter.
