OK.. I long while back I got an Addco rear sway bar 1 1/4" I believe. At the time I think I was told to reuse stock bushings and a little elbow grease. Everything has been fine. I am now transfering this bar to MY new cougar. I would like to put new bushings in. Which should I get?????? Stock size or does Addco have some special bushing for the bird/cougar?
