So, that was yesterday -- but since the question is asking about "today", here goes...
So suspecting the upper shift bushing, I decided to go in for a look. I had ruled out the lower one because yesterday I crawled under to verify it was still holding and in good condition. I figured it would be because I had replaced it about 10 years ago. But I did not do the top one then... (shoulda woulda coulda).
Anyway, I was pretty sure it was the top guy, and luckily I had a couple extra bushings I bought last time. I peeked at the Tech Manual and went in. Sure enough, once I managed to get a hold of the shift rod, the old one was cracked and just crumbled as I pinched it out of its socket. Following the steps below, I was able to replace the little stinker -- and once back together -- took another test drive! No tow truck needed this time!!

Buy a couple spare bushings to keep in your stash (like 3 bucks at most.) If possible, change both bushings at once, because if one is 52 years old, its gonna go sooner or later.
Yes its in the tech manual in sort of broad terms but here is my condensed step-by-step that might be helpful.
1. Remove carpet from floor and tunnel. These sections should not be glued down.
2. Remove for bolts holding shift gate box on. Be careful not to drop them in the abyss.
3. Lift shifter out of the way. Down in the tunnel somewhere is the shift rod, you have to find it and get a hold of it.
4. Remove broken bushing pieces from the eyelet if its still there -- other half might be on the shifter.
5. Heat up a cup of water in the micro to boil -- soak the new bushing for 10 mins to soften it a little.
6. Press new bushing into eyelet. Small hole faces drivers side (LHD). Attach shift gate arm mechanism to the shift rod, press it until its snaps in.
7. Reattach shift gate, reattach carpet. Be sure lever is firmly in Park when you start car. Test the shifter positions -- drive on!
This job could be done in less than an hour for sure. It could also be done out in the real world where you are stranded. If you keep a set of the bushings handy and have a pair of pliers, a 10mm wrench (and if possible some really hot water) you can pull off the fix.
Hey John, yes could have been worse for sure. Still humbling though to see the old Pagoda getting carried away on a stretcher... And Calli definitely enjoys the open air.
