.htaccess mod_rewrite - send all 404 to PHP script aling with full query string

I need a rewrite rule to take all unknown directory/file requests that have no match and point them to a specific url, along with the full query string of the original request

so I need this:
to point to:

And I need this:

I know this is wrong, but I think I am going in the right direction:
Options +FollowSymlinks
RewriteEngine      On
RewriteCond            %{REQUEST_FILENAME} !-f
RewriteCond            %{REQUEST_FILENAME} !-d
RewriteRule            ^(*)$ /index.php?action=oldLinkConversion&queryString=$1

Yes, very close. A period '.' (=1 or n characters) was/is missing in your rule-pattern:
Options +FollowSymlinks
RewriteEngine      On
RewriteCond            %{REQUEST_FILENAME} !-f
RewriteCond            %{REQUEST_FILENAME} !-d
RewriteRule            ^(.*)$ /index.php?action=oldLinkConversion&queryString=$1 [QSA,L]
