Differences between NA and NB?

Bodywise what is the differences/similarities between a MK1 and a MK2?
Obviously the fronts are different, but as for the sides and backs (doors, quarters, back panels) are these the same or is there differences in them. As in are they interchangeable?
Just out of curiousity, thanks.
