Help Removing windows on Bertram 25

just received a 66 Bertram 25 fly bridge. Going to do a total restoration on her. The side windows are cracked so they need removal which I believe I can figure out but tips would be appreciated.

The real challenge is removing the front windows because they have brown discolouration on the edges and bubbles in the safety glass. I looked at the window opening hinge and thought if I back off the aluminum strip at the top that pins the pivot point of the window that I could slide the window out from under the hinge. I can't get a ratchet with slot head bit on the screw heads because the hardtop is too tight. I have an angle screw driver but it is too big as well.

Anyone ever pulled the glass on these front windows before?
