I took one of your suggestions and put the TTrack Plus on the top and replaced it with a standard track. I made the support boxes shallower and added support on the top across the top of the saw fence. Then I dropped in some fasteners for clarity. I've shifted the positions of the slide-able sections to show the fasteners that would otherwise be hidden.
Addendum: The 1/4-20 screws that the aux fence sections ride on will be in threaded inserts (I have some from a previous project). That's why I'm not going to use track there. Should have been clearer on that.
