I have seen the install ocdart is looking for, nice and clean install and the shocks are way in the back not to be seen unless you crawl in the trunk for a ride..
OK, but still, why?
If a trunk torsion bar gets weak, it can be moved to the next hole, or easily removed and twisted a bit and put back in.
I have had to deal with many guards and deck plates on printing presses, modern presses use dozens of these things, and nothing's more maddening than having to always have to hold the guard up with your head, or have someone hold it, or rig up a prop, or go find a piece of wire to tie it up somehow.
They only work a few years at best.
If the pressman I know who almost lost his finger from a "slightly weak" gas strut were around, I'd have him say a few words.
