Drat, looks like all the plastic under dash mounting boxes are going to be just barely too wide for this, anyone have any ideas on that? I would love to find a seamless solution that would minimize any fabrication work. Seems like something like this Amazon.com would work perfect for anyone doing this on a 99-02 since you are relocating the buttons anyway. I'm going to double check with them what the dimensions of the box are though as I have about 8.25" inches to work with from the very edge of the hazard light to the inside edge of the bezel on the other side. It might JUST fit.

Amazon.com This one might even work better as it's tapered towards the back. Perhaps if it's the right size I could cut a din opening in the back and install this from the back. I keep some of that flang on there too to help with mounting.
