From levers there is rod down to autothrottle clutches, directly under pedestal on E-bay, from there all the way up to the each engine pylon you will find steel cables and pulleys, from pylon to FCU is teleflex cable.
....... with the TMS actuator the very last link between the teleflex and the FCU. I think the throttles could be a bit stiff. The fire handles/fuel shutoff were even worse as they didn't get used so often.
