Roof rack -- difference between glass roof and sunroof?

[dbartram]

I gather that roof racks for the Model S are different, for glass roof vs. sunroof models. Is that right? Does anyone know how they are different?

What I really want to know is whether a roof rack intended for glass roof would fit on my 2017 Model S which has a sunroof.

It will not work. Sunroof cars have a panel that goes along the edge and coincidentally, that is where the threaded holes are for the roof rack. The all glass roof, does not have this panel along the edge, and the rack actually goes around the glass itself because there is a little void in the area. I have had both cars, and both roof racks, and I can assure you that a glass roof, roof rack will not work on a sunroof model and vice a versa. To further complicate it, on sunroof cars there were two types of mount, depending on if the car was built prior to 2015, or after 2015. The rack was the same, it was just the threaded, mounting stud and door flap were different.
