A few questions please

Hello all
I am missing the keyed washer that goes in front of the wheel bearing in my 73 Dart. I was wondering if someone can direct me where to buy this.
Also I dont think tis brake line was connected properly, it mashes into the LCA I think the hose should be rotated 180 degrees. I dont have a service manual and cant seem to find a pic of it.
Also I was considering replacing these as they are cracked, where could I get the braided steel lines?

Many thanks
