I've been more of a lurker than a contributor on this website but that's about to change. I have an FJ40 project that I picked up about a year ago. I'm finally getting started on diving in to finish this and get it back on the road. One of the questions I have with this rig is how to identify where the shackle reversal came from and is there a lift associated with it? Rear shackle is 5.25" center of bolt to center of bolt, front shackle is 3" center of bolt to center of bolt. Pivot points are greaseable. Front bracket is approx. 5.5" from underside of frame to center point of bolt at front of leaf spring. Any insight anyone may have would be appreciated.
