I have this wild idea of installing vents into the pillars behind the quarter windows. Some 2-doors had vent windows, but they were right behind the front seats. My dogs often ride all the way in the back, and to allow air to flow all the way to the rear of the vehicle would be awesome. Plus, the slightly vent-looking moldings that were used here could actually have a function.
I have absolutely no idea how to make this a reality, however. They'd have to open and close, and seal tightly enough when closed not to be noisy/leaky. With the XJ being a unibody/uniframe, I'm also not sure if such a modification would affect structural integrity or not.
Any help or brainstorming would be much appreciated.
