I do believe the dimples inside the rails indicate ideal positions. That said it is the reason we were delighted to find a nice selection w/o sunroof. That + the extra weight, headroom loss, added heat load and complexity + we never open them (air noise, skin damage, and radiant heat). No matter what you won't want load borne on the glass panel.
