First photo shows the wiper blade location when parked, and second photo shows wiper blades at maximum sweep. Coverage is not complete, but favors the drivers side. These wipers will only be used in case of rain, and otherwise stowed away. The posts will normally have a finished cover over them.
Last photo shows the entire assembly from the inside. The excess portion of the drive cable that extends out of the tubing to the right of the transmission gets cut off, and a cover plate is bolted over the exposed drive to finish everything up.
