Sway bar bushing measurements
Hey guys, I've got a quick question.
I measured my front and rear sway bar today with a micrometer because I need to get new bushings for them. My front sway bar consistently measured in at around 36.1mm in diameter and my rear sway bar was in the 23.2mm range. I'm assuming that I want to get 36mm bushings for the front and 23mm for the back? Or do I round up and get 24mm for the back?
Also, my car isn't a 1LE. How is it possible that I have a 36mm front sway bar?

Re: Sway bar bushing measurements
I've got a 36mm front and 24mm rear sway bars on my 1988 Formula 350 with the WS6 suspension package. I think this was the same as on the 1988-90 IROC-Zs and maybe on the last of the 3rd gen Z28s. The 36mm front bushing are a little hard to find. I just replaced mine, took a while to fine some that would fit the stock brackets.

Re: Sway bar bushing measurements
Alright, cool. So if I measure 23.2mm for the rear sway bar, do I want to go with 23mm or 24mm bushings?
