General understanding - not on this car - is that you should not rotate the wheels any distance without the engine running. A short distance onto a low loader should be possible but towing with driven wheels on the road would be damaging. This is true for all autos in my experience. Ditto 4WD cars. When I took the RS6 they made a very clear warning about recovery through Audi by flatbed only.https://www.jimjenningstransmissions.com/faq/general-transmission/towing-car-best-practice/
I understand there is a dis-connect pin in the box that is very difficult reach, but have some distant memory that once pushed to enable freewheel it is a swine to recover. It would be part of the box so Morgan would not "drill it". Given how low the car is access would be fun.
I have seen cars towed with two wheels in "dollies" which are like small caster assemblies.
I have also seen cars dragged with the rear wheels up and front wheels on the ground, uncertain of the safety of this even with a steering lock.
I am not a trained engineer so this is all fully amateur content.
