yes.. the longer you can work with it before turning it into a million razor sharp tiny pointy knives the better it is for you.. so much less to worry about.. although I know everything there will be rusted together siezed up and perhaps painted over.. it is still worth it to work some magic there... spend some time and remove it in one piece.. might be a good place to use some liquid wrench or spray oil a few hours before you go working on it to loosten the screws up some.. I did a glass replacement a few months ago.. and although not easy to remove the screws..they did finally loosen up and started working their way out.. it was easily an 80 year old door.. [ maybe more ] parts of it were rusted through.. and I augminted the missing parts with spray foam injected into the cavities.. cut.. sanded and painted to become the pristine new door.. with new glass...
