door handle/mirror reinforcement plates

When I bought the car, the doors were really wavy around the handles. It's really thin metal and years of pulling on it cause it to move around. I assume B-bodies are the same way since they have similar handles. E-bodies have a little more reinforcement on the inside around the handles. The handles are also recessed slightly so the bends in the door skin strengthen it up more.

Well, I test fit the handles without the plates and I still get warpage of the panels when they are tightened down. Then I test fit a plate without any sealant. It still has warpage but I don't think quite as much. It seems that I'll have to live with it.
