I looked today at my car. The right side is what I posted yesterday. That side of the car has had a 1/4 installed long ago. It seams to be installed to low. They put two extra screws in the middle. The other side appears to be original and installed slightly higher. The back is defiantly more square than the front. I don't see how you could get them on the opposite side and have them look right. PM me if you need some more pics.
