I thought the Miscellany article was referring to a Type 9 box?
AIUI all 'quick shift' options basically move the pivot point of the lever further up the shaft, thus reducing the movement required of the knob, but increasing the effort needed to do so. You can do this either by replacing the lever or by spacing the existing lever away from the mechanism.
Shortening the actual shaft will reduce the amount of movement at the knob, but further increase the effort required.
Librands do a kit for the later box (MT75), but for the T9 box you need to go to either Burton or Rally Design. Simple extension kits are available on Fleabay.
