I can't risk taking it apart again. The broken part of the upper screw is stuck in the outer handle. We have lived in the house 4 years and our neighbor said the other people that remodeled was about 9 years ago. There are no visible marks, names or serial numbers on the parts. The 2 screws that hold the assembly together are 3 7/8 inches apart. Thank you for your help and of course I would purchase it from you.
