Hi there. I saw in your post that you cut the metal to allow for the seats to fold flat. I am doing the same thing with my 2012 Prius V but I can't access the metal on the larger bench seat. I posted pictures in the original thread. Would you happen to know how to access the hinge to cut the metal on that larger bench?? Thanks. https://priuschat.com/threads/rear-seat-modification-to-fold-flat.253244/
