This "Question Mark" extension based on RH12125 and RH9651 is necessary for removing the rack and pinion bolts on Turbo R's and is very handy and time saving for removing the bolts on all Rack and Pinion equipped Late SY's (Shadow II's) and all SZ's (Spirit/Spurs).  This tool is for the left hand bolt and may fit the right hand bolt as well for certain chassis'.
