after looking at the pictures, i believe i figured the most adequate spot for the shocks...
basically, you'll want the shock mounted to the arms, where the arms go lowest. or just slightly towards the hinge... because the way they are mounted now... when the trunk is closed the pressure is actually trying to push the trunk down. basically you'll want the strut to have a straight shot extending all the way right away... wheres i think the spot you have them at.... it compresses slightly and then extends
i know you just used an exsisting hole, but its just food for thought if you do plan on changing it... but then again if you are putting in a system you may want that little bit of pressure pushing down on the trunk to get a better seal.
