Out of another car and fabbing it into the existing switch panel. The driver-side switch is a little bit longer, so in order for it to clear where the passenger side switch is, the panel would have to be shaved maybe a 1/4 inch? I honestly haven't looked closely at it. The thought occured to me on the way to work this morning sitting at a light. I'm having a time finding a shop that will fill R-12 out here, so if I'm not moving I'm sweating and rolling down the passenger window with 1 touch would be nice..
