Hi James, if you lok from the front or rear of the car you'll notcie with your 3" lift kit that the axles are positioned over towards one side of the car, the idea of the adjustable panhard rods is that you can adjust them until the axles are sat centrally on the car. Not knowing where you got your rods from I couldnt say left or right hand thread, but if you go the wrong way the axles will be further away then ever. If you have standard wheelarches then you can measure from these to get the axle central, go for a run round the block and measure again. If you have cut wheelarches its a bit harder.
Hope this helps
Gary
