The CRX rear hatch gets attached flow, which should mean you can at least follow that slope down. You can probably even ease it down to a steeper angle. I noticed that your side profile shot is actually a little bit from above. You might get better use out of the template if you take a picture from about the height of the bottom of the window.
The video's been taken down, but you can tell from the ensuing thread that it was attached.
