My first post, so please forgive any mistakes!
I have a 2006 Ram 2500, so took great interest in your progress. Please let em know specifically what size screen you used and how you plan on installing. I have the radio bezel (with the knob cutouts, as opposed to the navigation bezel which is perfect rectangle). The dimensions are just such that you cannot use an 8" screen without having to do something about those radio knob cutouts, but a 10.2" screen is too large without major modification. My best option at this point is to order the nav bezel and modify it's rectangle, but I wonder what you did on your truck?
