Torsion Bar problem

I have a 1965 Barracuda, 273 torqueflight 904. My torsion bars are making a racket and I need to find torsion bar isolators or torsion bar silencers. Have been unable to find them on any site as of yet. Would anyone know where I might find this item.
It is making driving my Barracuda a real headache. I need some relief !!!
Any help would be appreciated.
