Wanted for 2004 thru 2010 Toyota Sienna (Ceres)

I have a 2006 Sienna limited.
It has the floor cut out, modified and lowered with a new section for a wheel chair.
My van is missing the built in 2nd row seat floor attachments.
I have the center 2nd row seat and am hoping to add it.
Im looking for a doner van floor to remove the factory "middle/center" seat floor section
