"Heavy" trunk lid fix
Do this, no drilling. Although in that picture, where it hooks on the left, its NOT the best place to put it, if the springs aren't quite taught enough they'll slide right off the bar.
Instead of putting it on the end of that bar, put it on the OTHER side of the flat metal piece, where the bar bends so that the spring can't pop off. It makes quite a loud bang if it pops off while the trunk is closed the way it is in the picture
