I have this same issue. I have an older speakman valve with the diverter located at the bottom of the valve but can’t find a trim kit that matches. All the speakman trims currently on the market have the diverter at the top. I’m thinking as a workaround I set the diverter to tub and just buy a spout with the diverter in it then I’m free to use whatever speakman trim I want.
