Alright so after I got home today I took things apart again to investigate the CLUNK and other noise from this morning and took some picture:
What it should look like:
Where it should go, notice the hole has seen better days:
So i ended up just pulling the bolt since it came out anyway and i'm certain was the issue with the noise I heard this morning after seeing how it has become mangled. I put everything back together without it, no more noise. I will plan to order a new one and possibly a new backing plate, which by my best guess after looking more closely today is secured behind the hub and park brake drum. In the meantime I will continue to drive the car, anyone have any reason why driving it as it is could be catastrophic? The park brake isn't very effective anyway so i'm not too worried.
