Nice, I'm lovin the wagon! Can't wait to see it mounted, I've always thought the 2nd gen Taurus has the perfect dash opening for a screen, but haven't seen one done yet. I had an 01 Taurus that I fabbed a computer into, I loved it. I've got an 04 now that I need to fab my AVIC Z2 navigation into since there's no double din kits for it. I'd go with a carputer but this Nav is left over from my 07 Civic Si I just got rid of and I love it too much to sell it.
Keep it up! Good luck if you undertake the swap, it's been done a few times and once that I know of in a wagon. Are you a member of the TCCA?
