Hi, I've got a question about my 40 ford rear axle assembly. It has a bar connected to a bracket welded to the passenger axle housing. Am I correct in assuming that it is a form of panhard bar? If so, would it be connected to the driver's side chassis rail via a bracket? It has a bushing mounted at the end. Were these common and is it advisable to keep it when I mount the assembly to the chassis? I hadn't seen one like this before. Thanks
