Thank you for your patience in this matter. Unfortunately, I have not been able to find a replacement for this handle set. From the description and picture I think it might be an after-market type, which means it may not be available any longer. Do you think you could substitute with a surface-mounted handle set like our 82-005? Look it over and let me know what you think of this suggestion.
