In response to Harley's comment: You are right on. I replaced my lower column bushing and the shifter detents feel fine.
Here's how I did it, for all of you in the future:
I took the trick from the Bird's Nest that mentions cutting it and slipping it over the column and into the tube.
It wasn't as easy for me as it sounds, but after a couple of hours of fighting and cutting and scratching myself, I finally got it up in there where it needs to be.
The bushing is made of rubber and is formed into a taper so that it wedges between the steering column housing and the shift tube. There is a little nodule molded on that wedges into a slot at the top of the steering column housing. The birds nest trick suggested cutting the bushing at the bottom (opposite the nodule) and slipping it over that way. Well the shifter lever (all of these parts become self evident when you're in there, by the way) is just too close to the column housing to make this a simple proposition. You're just going to have to work at it with a screwdriver and some other pointy implements to try to push it in there. I would suggest cutting the bushing at 3 o'clock (when looking from the engine bay towards the back of the car) where the nodule is at noon. This MAY make it easier to work the two loose ends into the column housing.
After fighting and cussing and forcing, I finally got it all up in there, EXCEPT for the very tip of the cut end, which feels like it is poking out very slightly. Since the cut ends are at 6 o'clock and therefore totally invisible underneath the steering mechanism, you can only feel it out and it is VERY hard to work. (Thus my suggestion of cutting it at 3 o'clock) Finally after pushing on that one end with a screwdriver for about 40 minutes over two days, I just said to hell with it and put the brake system back together.
The shifter feels totally great, by the way. I'm assuming that because the bushing is wedged up so tightly in the column housing it will probably stay put. If and when it fails, we will be able to use this post as an indication as to how long this workaround will last. I'm hoping for quite awhile.
One last note, don't feel sick after doing this when you go to start your car and it doesn't crank. The shop manual says specifically that after doing any shifter work on the column, you will need to adjust your neutral safety switch.
Good luck to all.
