I believe that you need only to remove the coarse and fine tuning knobs and that the "Bezel" (as opposed to the escutcheon which is a of the cabinet) and all else will clear the escutcheon and come out with the chassis. It appears that the mechanism attaches to the chassis with 4 bolts, and a setscrew for the capacitor.

This is a different mech than the "Magnetic" tuning, as far as I can tell. However, the magnetic tuning comes out with the chassis and can be separated from the chassis after removing 6 bolts and cutting 3 wires.
