The one great upside is that the Rod de Panhard stops the plate that the U bolts go through rubbing grooves in the vertical web of the Chassis Z section as the axle goes up and down. My 4/4 has barely 1mm clearance, the Rod de Panhard stopped the rubbing and delayed chassis repairs!
OK a sheet of stainless (?) inbetween the lower U bolt plate and the chassis would have worked too........ Regards PJB.
