[Theme: Customizr] Add content to right of navbar in header

I want to add content to the right of the navbar in the Customizr header that is the same size as the logo’s .brand span3 (25% width). So I know I’ll probably need to do something to change the navbar size to span6; similar to what is described here.

In summary, I want to center the navbar and take-up 50% width plus have two areas on the left (logo/title) and right (my_new_content) that each take up 25% width.

Do I need to use the __after_navbar hook? I need the content on the same row as the header and logo; not below. I’m not looking for a widget area; I need to be able to enter my own HTML/JavaScirpt/PHP.

Thank you in advance for any assistance! -Ron
