I went to install the neutral safety switch and found the shaft where it should mount has no grooves for it. I understand it must be for a manual transmission, although the lever points up. ( I thought on a manual it points down). I'm assuming that replacing it with the correct, original, complete unit(outer and inner shafts, with the grooves) is all I need to do to put it back to original and install the neutral safety switch. I have to say, the PO sure has caused me a lot of work correcting various things...from wiring to items such as this.
