my windows are 25 year old. Most are in good shape, but 6-8 of them need replacement hardware. My operators are 39-013 and 39-014. They are in good shape. I want to replace all hardware on the bottom part of the window, but not the top. I believe that the right hinges are 10". My window size is 25" x 50".
Is that all I need.
And how to remove the hinges if the screws are very rusted and not moving even when applying penetrating silicon?
Am I right to drill old screws out and placing new brackets/hinges in the same old position but by drilling new holes in between the original holes?
