upgrade from 4.04 to 4.05

[Kyle55155]

I am suffering from the missing cms button issue so I guess I need to go to 4.05. I have a lot of mods including manual code edits to the header template, navbar, footer, chrome, etc. custom images, etc, etc. I don't want to have redo all my manual code edits. Can I copy just the changed files from 4.05 plus upgrade.php and copy that to my existing forum directory and run the upgrade?

This is the list of changed files I got :
* group.php
* includes/class_facebook.php
* includes/functions_forumdisplay.php
