Steve, check about 4 topics lower on the page. There is a big topic about replacing the sway bar bushings. From replies I have read in here, the poly bushings are too big to begin with. They are 1", which is 25.4 mm. The front bar on a non SS is 25mm. Not 25.4mm. I got the correct OEM bushings at the dealer for about $4 a piece. They are very easy to replace. I think it took me under 45 minutes to do both.
Here you go.
