Disappearing door concept came along two decades before it was ever used on a Lincoln.
The Jatech engineers were heavily influenced by the mechanical concept pioneered by GM in the late '60s.
Although the disappearing door were not used as side entry points, it was successfully integrated as standard equipment in four models of the '71-'72 Chevy station wagon tailgates: The Biscayne wagon, The Caprice wagon, The Impala wagon and The Bel-Aire wagon.
This is one of the earliest videos showing a disappearing rear door as standard equipment in a full production early '70s Chevy vehicle.
