Pivot baseplate issue help

So I’m in the situation where I had to take apart the pivot baseplate a little as my brake got stuck at a bad angle. Long story short, I managed to get both brakes back into the black plate and got the spring under the plate but it wouldn’t stay down. I basically have 2 questions;

1) do any bits look broken? I think they look fine but I was putting a fair bit of pressure through when trying to get the spring down

2) is it possible for me to put the binding back together and if so, how?
