98 Ranger window trim question

Hello, I'm looking at a Ranger that has some rust and buckling under the window trim on the exterior of the door. I pulled it up a little and it looks like there might be a thin metal strip that holds the molding flat. I think that's what is rusting and not so much the door. If it is the strip then would that come with the new molding?

It's part number 5 in the picture...
