fj40 stock rear srings, sprung over, with axle pin moved back 1 inch, sring rockers, and traction bar, I also moved the rear shackle mount forward about 1 inch and used a longer shackle
front is stock springs, sprung over, reversed, and hung by some longer shackles (the trick was getting the geometry right so the shackle guset or spring dont hit the frame)
all this has gained almost more flex than needed, I used rancho adjustable shocks(cranked up for the streat) to keep it all in check.
