How To Replace Trunk Torsion Springs with Lift Struts

Scammer, I don't quite understand your mounting configuration, but here are pictures of my gas springs in my hardtop and they work just fine. It looks to me like the closure angle on your struts is too large and your are trying to overcome the load transfer from the spring to the floor. If I remember my geometry correctly, most of the load (trunk closure) is in the floor and that's why you are bending your struts.
Here are three pictures of how mine are installed. My trunk is upholstered so I can't provide any more clarity. Please notice the strut is almost completely horizontal in the same plane as the rear mounting point, if that make any sense to you. And in the third picture are the parts and pieces I fabricated to make it work.
Hope this helps.
