As you can see, fits fine and looks good. If I had not been able to convince Chris to do the Z3gato, my likely route was Cobra rear and sills, Z3 hard top and narrowed SWB front (a la WCA Z300). It still appeals.
Here is a pic of another with the OEM hard top. I was tempted but realised that taking them on and off is a bit of a pain. As is storing it when not in use.
