OK guys hopefully you can point me in the right direction. I've got a 95 STS that I'm putting back together. I would like to replace the sway bar bushings in the front since the old ones are shot, but I can't find them anywhere, including GM/dealers. I've got the 23mm bar in the front and the sizes available are 15, 17, 19, 21, 29 and 31 mm... has anyone else run into this? I've measured the bar several times now and it is in fact 23 mm. GM says it never existed... It was never replaced/in an accident, and auto parts stores/suppliers can't help either. I'm at a loss but need something to go on. ANY help you have would be a huge bonus!!
