Gas Struts on The trunk lid? Here you go.

Here's a quick video on the strut rod setup. You can see how even though it doesn't raise from the low point it's nowhere near falling. This is with 100lbs per side 15" rods. I'd like to try 120lbs rods but the smallest I see so far are 17" which means making an add-on to the L bracket on the floor. considering it.
