Jenn Air cooktop glass replacement

I need to replace a broken glass top on my cooktop. Looking at the part diagram-seems easy, just pull out top and unscrew the glass on the sides and middle-is this correct? Any tips?

That is about all there is to it. The hard part is usually removing the ducting for the downdraft to allow the cook top to be lifted high enough to remove the screws. But once you can get to them, but them out and the top will lift off the burner box.
