Replacing My Glass
The problem is the screws wont move . I have tried wd40 but they are completely seized. I don't want to break the screw heads, so I am reluctant to go heavy handed with them.
Answer Give the wd40 a good time to soak in if that fails try a proper penetrating Oil . If the glass is already out due to breakage you could always try a impact driver to move the screws. If all else fails then you I would recommend you re-drill and tap.
