I've got a jimmy fu case and was asking the same thing myself yesterday. The Davidsen dials are larger than jf cases and from what I can gather, larger than dealers cases too.
With the jf cases, I spoke to a guy that has fitted one and he said that will require a light sanding around the edges to make it fit. I'm not sure if dealers cases are larger than jf or not.
For some of his dials, I think it's worth trying to adapt it to fit. Maybe speak to dsn himself or some modders?
