It should go between the bar of the clutch and the head of the screw.  
The bottom hole (the one closest to the keyboard with the screen open) is 
the one where the clutch always breaks, so I would suggest you put it on 
that one.  There is a sound physics reason for this, which I was going to 
try to explain, but my physics is rather weak so after writing it all out 
I decided it would only confuse everybody.
