66 Dart GT HT Whatsitgonnabe?
I used a cutoff wheel on the inner sleeves on mine. I was pretty careful, still nicked one of the shafts. The rubber part i heated with bernsomatic and mapp gas and burnt it to get it out to save the outer shells. Then i saw the kits from firm feel with poly bushings, and greasable inner shafts, and decided to go that route. The first set of arms i dissassembled i had sand blasted and intended to use, but then sold since i found a set in the junky with factory swaybar tabs off a 74 valiant and grabbed em.
I think new shafts are available if yours is cut up pretty bad, or maybe somebody has spares they can offer you.
