Nath even with the old cockpit everything was totally flat on the canopy and forward wind screen. There was no depth to it in the canopy rails at all. It was even missing a portion of the wind screen.
Unless someone can post a definitive photo that is centered and taken no more than 6 inches or so from the head rest arguing won't change much.
The rails should appear to move out if your expecting to give the illusion of depth. The problem is it's difficult to do so with 3D games hence why there is devices out there to give you the illusion of depth while playing them.
Here's an altered photo of the original cockpit before this modification. Is this what your expecting for a centered forward view?
