Bob,
The hinged cubby box/arm rest was on the Phase 1 BJ8 only. (along with flat pull exterior door handles, glass behive shaped parking and tail lamps and no anti torque arms on the rear axle) The cubby box was incorporated with a longer console that came about 4" further back than the later ones, and met the cubby box. There was an open space of exposed carpet after that on the tunnel before the rear seats.
