Probably since the screen itself is so small you would have to get the dimensions of the piece.
the problem with 7" screens is they have buttons that you need to use that may be blocked by the bezel. same with the auto dimmer. so you may never be able to turn it off or use the volume controls or get to a menu.
When I was looking for my screen I found that the cheaper the better, yea I lose a little quality, but its not a huge deal since I have another one.
as for putting a double din up there its a huuge pita to mount it and make it stable, it gets very hot in there, and you have to hack up a lot of the "guts" of your dash in order for it to fit.
Another opt is to uses alpines vehicle hub or a clean sweep with a screen and a added dvd player or something.
