I just completed a shackel reversal on my 1972 FJ 40 using the Skyjacker kit wich includes 2.5" springs on the front and 4" spring on the back to level the stance. I welded tubes in the frame and used manafre's dogbone shackels and the stock hangers for the front, and the stock length shackels on the rear. My problem is now it sit high in the rear and low in the front. It takes 3" of lift with the floor jack under the front bumper to level the stance. I am thinking 4" springs on the front to replace the 2.5" springs may level it. Any suggestions?
