It says use but it is still in the bagPivot says used which means it has wear in the bore. Get a new one. Might as well change the front motor mount cushion while at it. All of the stock mount parts are fine. I'm not sure on the Poly vrs rubber thing. I've not had good luck with Poly bushings before. My case aircraft engine mount bushings. They sagged bad from heat. Went back to old school rubbers.
