Adapting Prius C trunk for tray

It's the upgraded c models come with that tray pictured and has different side panels for the tray to sit on when it's hatch is closed etc then I would say all that should fit in your base c but you'll need the pieces obviously from a car that's not like the one you have which is the base would make sense to me Corollas with SR5 trim had pieces inside that the base model non SR cars didn't have I used to put those pieces in my non SR cars all the time you just had to use all the pieces together to make the whole thing look and work generally Good luck
