Kimber sights seem to use proprietary dovetail cuts. I recently built a compact 45 and used Kimber's Meprolite tritium sights. I called Kimber and they were very helpful. They told me the correct dovetail cutters to use, and the depth of cut. I'm sure they could give you similar information about the sights on your project gun so you would be able to figure out what will work. However, don't be too surprised if nothing fits. Like I said, Kimber uses their own proprietary dovetail cuts for their sights.
