One of the issues with the dual sticks is the top tube of the stick mount is just below the seat pan. That is my interference problem. Also note that my interference is not ailerons, but the pitch axis. I thought it would be good to put in Rick's thread because they are related.
My original tapered hat section was no good. Not enough clearance on the pitch pushrod. So, I made a 3 piece version. Here is one side installed, and one in my hand:

I screw the other side down, and then put the top in. Those clecoes will become nutplates and #6 screws.

I did a trial fit of the seat pan and it seems good. I am going to extend the other two channels as well, so it is supported more than just in the center.
