The picture doesn't look perfectly level though either. The front end is slightly higher than the back end (referencing the trim piece on the door). But, its only about half a degree. So, the rear taper is probably closer to 13.5°.

Thanks!
I used a spirit level with a scale and found the following:
- 11 degrees - roof at junction with rear window mount/liner
- 21 degrees - top glass near glass mount/liner
- 28 degrees - middle of rear glass
- 31 degrees - bottom of glass near junction with mount/liner
When I did my tuff testing, I only had a middle and lower region tuffted. I have to admit some surprise at the steepness. In fact, now I'm interested in seeing if I can measure the depth of this turbulent area.
I'll copy this data under my original tuff testing and continue the experiment. I have some loaner vortex generators coming and we'll get a chance to see the effect.
I also have a Kovatch "filter separator" pressure gauge that unfortunately has a scale that runs 0-30 psi when I need 0-30" of water. I'll have to modify the spring and calibrate it.
