Tore out the rear axle over the weekend and the driver rear main eye leaf is bent and the pass side litterally was broke in half. They are stock springs with a 4" block. I want the cheepest way to replace em. I was going to go get a rear set from the J-yard but was told that 69-72 is a different beast than other springs. But then in the mags it shows rear springs from 69-89? FS. so WTF? can I go get a stock set of springs from any truck or k5? What about a truck pack? Anyone have some 4" lift springs FS for the rear? Or would I want a 6" rear? I want the static shackle it's a tow rig.
