Yesterday I took apart the windshield frame, separating it from the glass. The frame is held together by several little flat-head screws would just get stripped or broken off if I tried too hard to simply unscrew them. But after a session with my acetylene torch, they came out cleanly. The metal frame is in pretty good shape, but the glass was ordinary plate glass, not the safety glass the Ford originally used. Apparently the windshield broke once upon a time, and the owners were too cheap to replace it with safety glass. The next step would be to bead-blast and refinish the pieces of the frame, but that can wait.
