James, I think the knobs that you are refering to are designed to work with a rimlock door mechanizm. A rimlock mounts to the exterior surface on one side of the door. These mechanizms are still available through mail order houses (e.g. Home decorators) I've even seen them at the Home Depot. However, I dont know of any way to adapt one of these knob sets to a modern lock set. Good Luck!
