Here's the underside of the bottom trim. The securing brackets slide in a track on the underside.
Everything is in good shape.
The next step was to cut the sealant around the windscreen with wire. I did not get piano
wire as recommended, I got 27 gauge wire from Home Depot. When I tried it the wire broke almost right away. I resorted
to using a putty knife to jam in between the glass and the sealant, working my way all around the glass. It seemed to work
fine and the window came out with no problems.
