That looks great;, I have a 2000 X-star that I want to do this with. I've got a couple of questions about your project:
Do the gas shocks you got lift the hatch as high as the hydraulic cylinder did? I currently have to lift my hatch all the way up to fit a wakeboard in the rear locker.
Have you had any trouble with closing the hatch with the pull strap down?
Do you still have the extra parts?
I tried the link you had for the struts but i guess they no longer had that exact part, so i may have to search for a pair of similar struts.
