These were part of the "kit" that Wicks offered when I bought the original components.
A way to go before these are installed. But, this is what the interior upholstery will look like. These are the fore and aft seat cushions with the two head rests above them. The large wedge shaped things on the ground are luggage that is designed to fit, with the passenger in the aft seat, against the interior fuselage sides, up against the rear of the front seatback. Note the neat Long Ez patch sewn into them.
