Image extend right overtop sidebar

Hello,

I need an image on one page to extend all the way to the right, with the secondary sidebar beginning underneath it. The look I’m going for is the (static) front page look, but with a single image instead of the feature slider.

Using the default page template, what CSS could I add to make the secondary sidebar begin underneath the image?

At the moment the page has no secondary sidebar. https://www.gabrielsolomon.net/suzuki-program/
