Yes, it does, as does the MD-11.  Not sure of the details of the JAL
DC-10's, but I suspect they took it upon themselves to remove the
center strut after delivery.

Can be, but requires deflating the strut.  Then using a hoist, the
gear is slowly lowered and pushed aft until the lock links go over
center.  Finally, the strut is reserviced and is ready for use.
