There's 1 problem i see, the plates that tie into the frame rails are straight in your picture. Where the sway bar needs to be mounted in the chassis, the frame rail is not perpendicular to the sway bar. Secondly, what type of bushing or bearing to you plan on using for the sway bar to ride in? And lastly what material is the sway bar itself made from? I looks like you're on to something, keep up the good work!
