I wish you the best, but I believe you have solid color seats. Check out the sales literature and Ford's web site. Black refers to the dash and other such parts. Chamois, I believe, will be solid seats and part of your door panels.
I have researched this and researched this. I know of two-tone seats only on the California Special.
And, I'm sorry to say, dealers and sales people are not experts on this. Anyone who reads the brochures and studies sites like this usually know much more.
