Custom Post Types and Page Templates

I am using Custom Post Types with a Faceted Search Widget. The issue is applying a ‘page template’ to a CPT. I have set the Sidebar on Single Post Pages to no sidebar and inserted the faceted search using the drag and drop page builder in Enfold. However I lose the ability to apply a sidebar to any additional CPT.

What I would like to do is set the Sidebar on Single Post Pages to right sidebar and remove the side sidebar from one page only. So all posts have a right sidebar except one.

Or better yet create different page templates and apply them to the CPT. I have installed a plugin that allows page templates to CPT, but only see archives and blank – no header/no footer.

How do I create additional page templates or remove the sidebar when preset by Sidebar on Single Post Pages?

Thank you!
