Thanks for contacting us! This is an old discontinued Silverline Swinger window. The hinges should match with our 15-058, however they aren't made to be replaced. There is no easy way to get the old ones out, I'm afraid. I've known some people who have drilled out the old rivet and used a large screw to attach the new hinge, see if that could work for you. |
