The neutral safety switch is at the bottom of the column inside the interior compartment. You might try to adjust down there. Or do what khaley71 recommends.
Wrong The switch is screwed into the left side of the transmission. It has 3 wires, 1 for NSS operation and 2 for reverse lamps.
There are pictures of the adjust block on the first linkage rod away for the trans mounted lever. Only the one bolt in that block to loosen and retighten again. Hard part is jacking the car up and supporting properly so you can get at it.
If you don't have proper jack stands or other available,
Please do shift the column around inside the car seeking a sweet spot. That may not work but its better than getting squished to death under the car.
