 The 1971–72 wagons featured a 'clamshell' design marketed as the "Glide-away" tailgate, also called a "disappearing" tailgate because when open, the tailgate was completely out of view.On the clamshell design, the rear power-operated glass slid up into the roof and the lower tailgate (with either manual or optional power operation), lowered completely below the load floor.The manual lower tailgate was counterbalanced by a torque rod similar to the torque rods used in holding a trunk lid open, requiring a 35 lb push to fully lower the gate.
