1965 Valiant bench seat seatback issues

Here's mine. This is in a 64 Valiant 2 door seeedan.
Here's how mine is attached on the outside hinge.

And the back of the seat bottom where the back of the seat rests. I think this is where yours is broken. There's also something obvious going on with yours on that inside hinge area as well, not to mention that ridiculous clevis pin on the outside. You just need to get it apart and "see" what's going on. You may end up needing another seat frame. I just don't know.
