im going to have to advise against it. the problem is, while it corrected the camber, it had the caster way off. caster could not be brought back to a safe level, thus they came off.
if you still want to do this, and dont mind your truck hydroplaning or changing lanes on rough expansion joints on interstate, then all you need is the DJM lowered upper control arms for a 98-up Ranger. i extended mine exactly 1". most machine shops can do this.
once again, i would not recommend doing it.
