anyone done a full bushing kit to their s13? i’m having trouble with the rear. i know for the lower control arm and one on the spindle you need to saw out the metal collar things, but do you have to do that on all the other ones? it says to press the bushings out, but i just burnt them, so the metal collar thats between the arms and bushings are still there. i tried to put the new ones in but they wont go in even with a press… please help if you’ve done this
