KB I don't have an answer but if you don't hear anything here encouraging I'd call Incra themselves. They have a very friendly and helpful support staff that will likely have many ideas that can assist. In fact they have a project book that may have some ideas that will work with what you have. Can you posy a few pictures of the complete setup you have now? I have their LS Positioner and Super Fence but mine is only a few years old so not likely to look anything like yours but may give some hints as to what path to try going down. And they also stock a good deal of parts in case you're missing anything....
