Nice pictures Pat. As always - top notch work.
I have the Classic Air system, and it is set up much like this. In my case, I had to block off the passenger vent, although I was able to keep the driver vent. In my opinion, it is still really nice to maintain the use of these vents. They work really well and there are a lot of situations where you can use them. In your application, it looks like you could get a driver side vent and adapt it to the passenger side and maintain the use of a vent. I throw that out there just for your consideration...
The other question/comment I have is about the wiper motor. I am sure you checked, but do you have enough room to allow for the wiper arm swing? It is hard to see in the picture.
Really clean and nice installation!!
