G`day
At your own risk ,
i do this with an old falcon that gets moved every 4 or 5 yrs , of coarse the landrover has bigger moving bits but this may help .
You could try momentum .
May not be pleasant .
One wheel off the ground , started in high range , highest gear .
Use the throttle and brakes , it won`t sound nice but if nothing lets go it may free up . ( coarse with your foot on the clutch pedal )
If the plate etc was in good nick probably only one way as you say .
Cheers
