Unable to shift his T90, How does he remove the fork if he can't pull off the throw out bearing (we suspect it seized and is friction welded to the shaft) as you're supposed to in order to get the fork out?

Something else is amiss. The throw out bearing rides on the front extension of the T 90 on a "slider". It can't seize to that. Has he removed the inspection cover and looked at things in there?
He can't shift the transmission shifter cane at all?
We need more info to help solve his problem.
The two normal situations that come to mind are either the input main drive gear has stuck in the pilot bushing, or the clutch friction disc has rusted and stuck to the flywheel.
I've also seen clutch discs come apart and all the pieces swirl around inside the bell housing and wreck things.
See if he can give us more to trouble shoot with.
He may have to pull the bell and transmission off the engine if all else fails.

Sounds like you are describing two different conditions here. Not being able to move the throwout bearing is a clutch issue, not a shifting issue. If his problem is really that he cannot move the shift cane to change gears, then his problem is inside the tranny. In that case I would take the top off the tranny to look inside to see if something came apart and jammed the gears. That will allow him to make sure the forks under the shift cane are not bent the wrong way too.
If the pilot bearing is not moving on the input shaft, I'm with Oilly on the causes. The most common problem I've seen is the clutch is rust-welded to the flywheel. That can often be solved by opening the inspection cover and driving a flat-blade screwdriver between the clutch plate and the flywheel. That usually breaks the rust-weld and then the clutch is free from the flywheel.
Good luck with this. Let us know what the problem turns out to be.

I have suggested he come here and interact directly because this is not my forte. Unfortunately, he doesn't want to. So. One more time:
"Rick, I can shift the shifter thru all the gears very easy w/o the clutch and engine off. I don't believe that my disc broke apart because there was no noise. I was able to start the jeep in gear and drive the rig back into the garage in low range, I did that as to go slow. No noises. I did notice that the throw out bearing is stuck right against the fingers, that means that the bearing seized while the clutch had pressure on it. Normally the bearing is back a little from the fingers."

Out with the engine! 😮, if the TO bearing seized it usually wipes out the fingers on the pressure plate, but that usually makes lots of noise!, but it would explain why he cannot release the Clutch!.....

Just wondering.. A. Sudden onset? (shifted fine yesterday now not). B. Ran when parked, just now pulled out of long term storage? C. New purchase with no known history? D. Recent work done on related components? You know, that whole "inquiring minds" thing..  |

Does he have any travel when he pushes down on the clutch pedal? I suppose the carrier could have rusted to the bearing retainer...but the carrier is constantly sliding back and forth on the retainer. Has this Willys been sitting...not moving...outdoors for a long time? If this CJ has been a consistent driver, then I'm thinking this may be a linkage issue up stream from the throw out assembly.

Who put the transmission back in? New Pilot bushing?

First, reach inside while not running and see if he can pull the throw out rearwards. Besides the clutch linkage adjustment being correct with petal play as per manual, is the little return spring still good on the throw out bearing carrier? Passenger side of the carrier.
If he can pull it back, he will be able to spin the throw out bearing with his finger if still good.
Report back after this check.
