I just bought a used rear Con-ferr axle truss. I have never used or installed one of these before. I got two perches that appear as though they sit under the axle, two new u-bolts for mounting the perches, and the truss bar itself. I noticed the bar has two nuts on each end. I am assuming one goes on the inside of the perch and the other on the outside to essentially clamp the truss onto them. But, where do the perches mount? Should they mount outside my spring u-bolts, i.e. between the springs and the hubs? Or do they mount inside the shock mounts? Seems to me this would be too close together. And I assume I tighten the outer nut first then lock the truss into place by tightening the inner nut up against it. But how tight do I tighetn the outer nut? As tight as I can? Or is there a torq spec? Any help would be greatly appreciated.
