im trying to get the old bushings out of my yj springs and am having some trouble. the smaller end i was able to pound out with a hammer, but the larger end with the metal sleeve over the bushings is not budging on any of the 4 springs. all four came out of the others though. anyone have any advice? also im in the process of turning the center spring alignment pin around and one is toast, anyone know where i can get another one? thanks guys
