3 Here you can see the side-by-side of the old piece (left) and the new donor piece (right). You might notice that the factory piece has a different opening for the A/C compared to the new piece, which is from a non-A/C car. Since we will be using an aftermarket A/C system, the car is being converted to a heater car so all the new aftermarket stuff will fit like it was designed. Also, look at the bottom right side of the new panel that is the brace piece that was removed earlier. At the time of the work AMD did not produce these panels, but they are now available so there will be no need to find a good donor car.
