Rear brake backing plate

I have a few rear brake backing plates with the anchor broke off. Does anyone make a replacement ? Is the anchor heat treated ? I have thought of making some. We have a nice fab shop to use so this isnt a home repair. Any info appricated

Iff you make some I'm interested in a few to.
I wonder why they get F***** so often....

Axle sleeve nut isn't tightened enough. I think a lot of people didn' have a proper tool and snugged with a pliers or something. I would like to have some replacement stops too, if you have some made up Chuck.

Looks like we might be making some up then, thought I was the only one with broke anchors. When I find out about what type metal and if heat treating is necessary, I will get on it.
