Rear Seat Trim

I'm looking for rear seat trim which covers the battery. When I bought the car (2012 Prius C), the trim wasn't included. I've searched ebay and junkyards but I'm not able to find all three parts (I found 2 for an *okay* price but seems expensive for what it is, $90 for 2/3 parts and the 3rd part is $90+ through Toyota) Any tips? I've called about 20 salvage yards in Chicago so far! Attached picture to show the missing parts.
