Pull up the rear seat base.
Middle of right seat and middle of left seat. Reef on it hard. Pops out.
Then you expose the start of the other 10mm bolts holding the seat back on.
Remove the rear c-pillar trims. Pop the tabs out marked SRS. Screws are behind that.
The rear parcel shelf has to come out.
I can’t recall what I had to do to the top of the middle seat belt.
