After re-reading your original lockup symptoms, it appears that they have disappeared after pulling the driveshaft. That sure tells me that the third member and/or the shaft is where I'd be focussing my efforts.

Tried to get the car out this past weekend but it went downhill fast.
Here are I believe are the pertinent facts:
1. Small blk with Passon Alum 4 speed 6? years old, , 2000 trouble free miles, has sure grip, OEM tapered axles. 2. Car has seen no miles in 4 years 3. When car sits on jack stands, rear wheels and DS turn easy by hand when in neutral both ways, engine off. 4. Engine starts fine, pushing clutch in tranny goes into any gear fine. 5. When letting clutch out when in 1st gear on the jack stands, unless revs are brought up to say 2500rpm engine dies, and wheels still turn very hard/slow. 6. Pushing clutch in with trans still in gear and with wheels still turning, causes wheels to immediately to lock up. 7. Above is the same in 2nd but much harder to get wheels to turn, reverse the same, can't get wheels to turn without killing motor in 3rd or 4th. 8. I can get trans side cover shift levers into all normal? positions from below
Nothing indicates to me clutch/pressure is stuck. Not sure if 8.75 could lock itself up. Everything goes south with trans in gear?
I'm at a loss, and am trying to eliminate as much as possible before yanking trans.
I have called Jamie and we are scratching our heads.
Any ideas?
After re-reading this again and again, unless I'm still missing something, it seems to me that one of your main drive gears in the trans is frozen to the output shaft. With the car on jack stands and the drive shaft out, put the trans in neutral. Go under the car and see if you can turn the output shaft of the trans.
4 speed street legal. Best time 10.99 @ 124 mph on 93 octane pump gas @ 3926# total weight

Thanks again guys for all your help. 1. Carrier is MP alum 742 2. When problem first was noticed wheels were all on the ground, when raised, the rear jack stands are under the housing near the leafs, ie not hanging, but at ride height. 3. I will try tonight with a helper to hand turn a spare yoke with clutch depressed. 4. yoke bottoming does not seem likely 5. Original yoke slipped out when dropping DS with no issues 6. I don't know enough about 833 internals to reply on whether a gear has frozen to a shaft. We will try again tonight.

This will prove nothing. Try turning the output shaft with the transmission in neutral and the clutch pedal engaged (foot off of pedal). If it doesn't turn or is hard turning, then one of the main drive gears is too tight of the output shaft.
Either that or the cluster gear is froze onto the shaft...

So tonight i have a helper: 1. I verified the same problem as discussed before, no differences. 2. I pulled DS, rear yoke turns fine, wheels spin freely car on jack stands on housing. 3. Engine off in nuetral tranny clutch out No DS, tranny yoke spins free 4. Engine off in 1st, No DS, clutch depressed, tranny yoke spins free 5. Engine running, no DS, letting clutch out in 1st, no bog, tranny yoke spins free, and stops pretty quick when depressing clutch Unless tranny needs a load to lock up, the above points to the rear end? I might take a day off on this. Could a brake somehow decide to always drag under load? The rear end when I let out the clutch looks kinda of "grabby" before its starts to turn and then engine dies unless revs are way up. It has tapered axles and maybe I should pull the drums, to see if a mud dapper wasp made a nest, or something. Not sure which is more work or more certain, install another complete housing/3rd member w/brakes I have laying around and test, or yank the drums and then the carrier and keep hunting the problem. Regardless the Alum 742 has to go back in eventually. Jamie if you see this latest post let me know, I will be contacting you regardless when something is known for certain.

Maybe a stupid question but is your emergency brake fully released??
The way I see it, If all was well when last used and lube was not drained, Manual transmissions and 3rd members normally do not deteriorate from sitting. My money is still on something in the brake system. Try running it with the rear drums removed.
