Outer Limits 4x4 Board

Just done a SAS on my runna, leaf sprung.coils rear.. my prob is , i dont kno wat to to with the rear setup>>Arms are too short, was thinking of a 4link setup rear.. but have to chop the main tank, and get a custom.. would like to keep tank if possible.. but want more travel in the rear. its has 5"80 series coils in the rear.. 2"leafs+xtended shacles and 2"front drop. in the front>> front end travel really well... the rear used to ravel perfect when i had the 4" procomp kit in>. know has gone all funny..
any info would be great>>

make some custom rear trailing arms up

Have already. top arms and bottom , but when it travels it push's the tyres into the rear bumper /quarter panel..
thinking of relocateing the the bottom mounts forward ,and off setting the ends of the top arms to clear the tank. i have seen both 4 link setup, and the one i just metioned done by ori on 2 of my mate's runners but just cant deside on wich>> [color=blue][/color]
