what size tires in the front? out of curiousity, could you take a shot of the LCA from the front? trying to figure out how you got it that low and still have any suspension travel. I think I'm at 25.5" on my duster with 195/70R14 fronts and I still had to cut my front lower bumpstops to have an inch of clearance between the bumpstops and frame.I'm at 28" in the back and 24 1/2" in the front.
When you find that shackle, post it. I am looking for the same.SS springs with 275s. Looking into a shorter shackle now to bring the rear to a respectable position.
