Replace or not?

[J48chevy]

Curious what the "experienced" builders on here think about my dilemma. I just had my truck stripped down and guess what, more rust spots I did not know about. The 2 pics show this. It is the inner cab panel around the 3 windows. My big question is it is below the back center window and a little on the drivers side below corner window. Would you replace with new entire panel or patch this one? How hard is it to remove the interior panel as I am sure there are 100+ spot welds. Or do I keep original and patch it? I am new to all of this and not sure which way to go. Just not sure if I am capable of doing entire panel or not. If anyone has replaced, please share. So thoughts are appreciated. Thanks.
