So, I bent the backing plate for one of my drums while attempting to pound a bearing out (lesson learned). I think it might be able to be straightened, but would rather just buy a new one. My problem is that everywhere I go for a compatible backing plate shows me one that looks like a later '80's backing plate. Mine is definitely different. It has a post at the top above the cylinder. What toyotapartsdeal.com sent me looks like a later model. Can I still use it? I'm kind of lost on what parts I'll need to make it work. They sent me part number 47043-35150, but my actual passenger side backing plate looks more like a passenger side version of 47044-35110.

What I have: (it is upside down, but notice the pin in the bottom of the picture, which is actually above the brake cylinder)



What they sent me:

 

If you are just worried about the dent in the outer edge you will have no problems straightening it out and re-using it. just make sure it doesn't scrape on the drum.

 

Unfortunately, it was bent the other direction (towards the shaft on both outer sides of the plate). I was able to pick one up at a Yota junk yard at lunch today, so I'm back in business. I wish I had gone there in the first place....I was able to pick up a taillight lens while I was at it.
