55.2-59 How to fix this - after patch panel

[FAKKY]

Hey guys
I had bad rot in the doors and decided to cut them out and replace with teh lower weld in units.

So when I patched these in ......... looks like I now have this issue. Basically the metal above the weld is kinda bowed out (almost like its too long). I know theres various ways to shrink metal and assuming I have some hammer/dolly work here ... but just not 100% best way to approach as never done before.

Up for thoughts.
