The 556 mod in the E put a 3 position pinky switch on the left throttle for radar/heat/gun.
....'fiddly small', however does apply to anything in the F-16A cockpit, including the amount of residual space.
Many thanks - the report made it sound as if the plastic extenders were a feature of many an F-4 cockpit. Probably a good reason for not putting flight critical switches near more mundane selectors.
