They are the same body style, and but they tweaked a few small things over the years. Because of that 99% of them are the same, but that 1% differs. They changed the sound bar, and seats, climate controls among other stuff. Not real sure about the specific changes to the tops, mostly color, but I think they changed the zippers too. From other threads here on the forum, you may be able to use a whole top on any year but would need to be careful replacing parts due to color and zipper changes.
