Angry-sasquatch has a point, bluntly put, but what he was trying to convey was that, because those two pivots are solidly mounted in the frame, thy would push it apart when they extended and the shock compressed, breaking the frame.
I hadn't thought about that, but it would be easily solved by putting a small link between those two pieces in which the rear triangle would pull straight down on it...by the way this isn't something I am serious about at all...I was just very bored one day and decided to draw an undead that would compress from both sides...don't think I'm trying to start a company with this.
