I worked on Mopar police cars for years starting in the 70's. It was in the colder climate of Ct. at the time. They used a lot of salt on the roads during the winter. The salt etched the torsion bars, especially the bent bars of the F body cars of the 80's. Quite a few times walking out to the patrol lot in the cold mornings you would see cars leaning to the side with broken T bars. This was due to the salt getting into the rubber support bushings, etching the bar and causing it to snap. Bill
