Backing Plate emergency

I was hearing this loud click on the 1-2 shift, and found my RH backing plate on the pass. side rear brake cracked and rotted up near the anchor bolt at the top.

That's not good. : (

Is there a repro for this or am I going to a boneyard?

Also.... is this one of those "68-72 any A-Body will fit" thing?

Thanks!
