On the windshield glass just take a razor blade and cut the seal along the edge of the glass and then remove, you will need a new windshield seal anyway,take the good pane of glass to a local shop and have them use it as a pattern to make a replacement then order a new seal from "Steele Rubbber".
On the back just find the end of the lock strip use a small flat head screwdriver to pick it out grab the end then pull it out, after the lock strip is removed a little pressure from the inside from a helper the glass will pop right out as you catch it on the outside.
