What's the safe way to unhook the propeller shaft to tow a 210 with the back wheels on the ground?

Can the shaft be swung out of the way after unbolting the rear flex disk from the differential, or do I have to unbolt the center carrier bearing?

Should I unbolt both flex disks and the center bearing so I can take the whole shaft assembly out of the car?
