Nolan, Did I understand you correctly... The main bar attaches to the frame rails and the end links attach to the spring? That's the opposite of what I understood from the pictures I've seen in this thread.
Also it looks like Greg's rig has the axle on the top. like mine, from the pics on this link, and that it is a factory unit with the main bar attached to the axle. Your's looks like it might be an aftermarket unit with the axle on the bottom, but it too looks like the main bar attaches to the axle with a "U" clamp. (Can't see the mounting of the end links to the frame rail.) If true, that unit with shorter end links might work for me.
Am I on track, or even more confused?? Maybe when I see your's and Greg's pics, it will be clearer. Tomorrow I will get under my rig and take some pics of my own.
