Rust repair around striker in door frame?

I know what you're talking about, but can't find it. It was on a primered Cuda. I think it might have even been in that mag that got swallowed up by Mopar Muscle. Seems to me that they put a plate in behind to support the striker post.

That sounds right.
Well, it appears there are several options. The Dynamic looks good, but may try the plate with screws first. I guess I could always make that plate, and weld it instead of screw it, grind and paint? That way it would have substantially more strength in that area?

Thoughts?
