So I noticed the other day while my 89 GTA was on the lift that my sway bar bushings are shot (as in have completely rotted off.) I didn't know until I went to order new ones that there are different sized sway bars and you need to know the size before ordering. Is there a way to measure to find out what size? And yes I realize this was probably a stupid question but I'm new to working on cars so please be patient with me. Lol

GTA would have a 36mm front bar.
