remove whatever is in ur way, dont be afraid of breaking ur car first of all, remove ur seats if they are in ur way, but a short shifter is quite easy once i just go at it shouldnt take more than half an hour to do urself, dont have an accord though so i dont know what ur looking at but its the same for any car, remove center column by undoing the screws, undo the screws holding it down and undo the screws attaching it to ur shift linkage, and then put it back together without too many extra screws left over, enjoy
