Just moved into a home. Seems some of the windows will not stay up. Looks like the window shoes may have broken (see attached pics). The windows do not have any sort of brand marking on them so I do not know what it is. I am not sure what type of shoe or coil I need or the poundage it may be either. I have attached a few photos for you. Thank you for your help on this.
