I just picked up a 75 fj40, SOA , 60 rear springs on the front, shackle reversal and the shackles on the front are resting on the frame on the flat. The shackles are currently 5" from center to center of the bolts. I need your opinions as to how to fix. I can put on longer shackles, if I go to about 6 1/2" center to center it looks like it would fix it. Or I could move the frame hanger back. I know Mark W is high on long shackles. What do you think?
