How to take backs off split bench seat?

[ESP47]

I'm redoing the upholstery in my 71 Duster. It just has a basic split bench seat but I can't for the life of me figure out how to take the seat backs off it. I figured there would be a bolt to remove but there isn't. It almost seems pressed in or something with a post going through the hinge with some sort of washer on it. Anyone know how to disassemble this thing? Thanks.

edit - never mind I figured it out. just had to take that one washer off lol

Man, am I glad you posted this. I never would have thought that little washer was the only thing holding the seat back on. Thanks!
