I believe you should have gotten an email from us today in regards to this!
I did and thanks for the email. I just haven't had time to respond until now.
Unfortunately I didn't take pictures of the issue, and since I solved it and everything is installed on the car I don't plan on a removal any time soon!
The area that gave me issues is circled in red below:
The phillips screw would not tighten down despite the other three tightening fine. When I removed the screw that was giving me trouble the first 1/4' or so had black plastic wrapped around the threads. Looking down inside the hole it looked like there may have been multiple "holes" in a black piece of plastic inside the wing. The only thing I can figure is that this was caused by the factory or by the window tint installer as they "had" to remove my wing to properly fit the 3M crystaline to my back window.
My solution was to use some BluFixx in the holes and then install the riser. The end result was a screw that was firmly in place, but still allowed the riser to rotate a bit. The rest of the install went fine and everything looks good although I will most likely be paranoid about it for a while!
On a side note I did have to buy a tap to chase the threads on two of the risers which didn't totally surprise me since others have had to do the same.
I do appreciate you responding though. Hopefully my situation/mistake/freak occurance can help others.
