G6 panoramic sunroof question

Has anyone had their headliner out who has the 4-panel sunroof? I want to know how far out the rails and tracks for the sunroof go out. Like do they go right up to the doors or do the tracks pretty much go right under the outer lines of the visible sunroof?

Im grafting the panoramic roof into my Cavalier and Ive got 2 salvage yards who are willing to cut the whole roof off smashed G6s. The one place I want to get the roof from cant cut into the pillar that runs from the front rocker all the way back to the 1/4 panel(the roof rail) otherwise they will have to charge me for the post which is big bucks.

Any help would be appreciated

Any yes everything has been measured out and calculated so dont tell me it wont work. Ive already been told I cant put scion tails or RSX headlights on or convert it to RHD.............and its currently being done. So keep the negative BS out of here. Thanx
