The metal bar that was placed behind the thrust levers was known as the 'Bodie Bar'.........
I must admit I had never heard it called that before, but it makes sense as the Jt9d did have what was called a
bodie tube fitted IIRC between the 3.0 bleed actuator and the no.3 3.5 bleed valve due to the (early) engines habit of going sub idle and running down. (Now scratching the grey matter here BUT the loss of fuel pressure ensured that the 3.5 bleed valve opened to offload the compressor.)
