I screwed up, neep help

Keith, the clips hold the 2nd trim in place which I now know. I am going to attach a pic that shows 2 trim pieces go around the side and top of the rear window. Im sure that there is a way to do this but it looks like a ***** to get to. I will try making a screw driver just for this if i have to. I really dont want to remove the glass again. Although the back looked much easier to do then the front was! I dont have a close up of the back trim but here is a pick the shows 2 pieces of trim the outside trim is the one that should have gone behind the clips and then the clips hold the inside piece in place.Copy of IMAG0004.jpg
