@branddooon i know what you're wanting. As far as I know they don't make them simply because theres not much to see. Its not as cool looking as you're thinking.
I see. You are looking to replace the original housing of the iPhone and not merely just a case. Got it. Sorry, I haven't seen anything like that. You might want to check the repair shops like iResQ. They may have something like that or know of a place to get it.
