I have installed and rigged my elevator bell cranks and push rods. The final step for rigging is to check the flight controls for freedom of movement. While doing this I found that the forward elevator push-pull tube rubs on the underside of the center seat belt mounting bar.

I tried shimming the bell crank inboard, no joy.

What should I do?
