Yeah the center mount like that would work. Using the last hole in the arm will take some work because this ram is so large and the factory bolts are in the way. Maybe building an extension mount like I did on the other arm would solve that. It just needs to be really strong. I'm not sure how much I like the mounts that clamp to the tube. Maybe it's just me but I worry about unnecessary stress on the tubing given that there are critical moving parts inside. But it should work out great.
