Right quarter window replacement

Yes I have the service manual and it shows replacing the window with the trim panel removed. There are 2 holes to access the bolts easily with it rolled about 3/4 up. With rolled all the way down, I can access the forward bolt easily, but not the rear one. Can get a boxed offset wrench on it, but not much room to move it. Even if I can it loose and off, reinstalling it would be extremely difficult as there is no room to get your hand in there to start the bolt.
You mentioned pulling the stainless trim, how is that held in place? Clips? When I remove the screw at the rear and work forward do I just carefully pop it out?
