Mark:

I did make substantial cuts in the vertical portion of the dash to clear the flexible tubing that connects the plenum ducts to the dash ducts on both sides. I also cut about a half inch off the plastic duct fittings so that the flexible duct would fit a bit better. In retrospect, I should have located the plenum ducts further forward about an inch or so, so that the flexible tubing would not be so cramped.

Hopefully this pic will help. With all the pics I have taken I can't believe I don't have something better to illustrate it.
