Mine's apart right now, so it should be easy to measure accurately. Please clarify exactly what you are looking for. I would interpret the rear vertical cockpit panel to be behind the rear seat, and the rear vertical trunk panel as what? The rear shroud, which is a body panel, makes up the rear of the trunk, which attaches to a frame that also supports the strike for the trunk latch. The panel behind the seat slopes, so the exact point of measurement would be critical.
Let me know and I will get you the info!
