I just got front and rear sway bars from a 88 Z28 from Pull A Part and I know the rear is 24mm but keep getting different measurements for the front in different places. It is a hollow bar and had an extra bar attached to the sway bar that bolted where the bushings bolts. I just can';t tell if its a 34MM or a 36MM and don't know what size bushings to get to replace them. The factory bushing that I took with the bar has this stamped in them, "clevite 9" then under that it has FG on one side and 81283T on the other . I have done a search and cant find what size this bushing is anywhere on the web. I am using a crescent wrench to measure with and get different sizes in different places. Also what is this other bar that attaches to the bushing bolts called?

 

My guess is that you have a hollow 34, solid 24 combo. The second piece sounds like a Wonderbar (these were stock on IROC's).

ok I got one of those digital calibers from Auto Zone and it says the front was just as you said 34 front and 24 rear. Its actually a little over this size but figured the paint made it off by a little. now two last questions when getting the bushings for the front I see they have 33MM and 35MM bushings, which ones should I get for the 34MM bar, the 35MM? and should I get 24MM for the rear even though it was a little bit larger than 24Mm or should I get 25Mm bushings for it?

 

Measure where the bushings attach. That's the part you're concerned about fitting into the bushings anyway. If you don't have a micrometer take it by a parts store and borrow the one they've got behind the counter.

 

If you have the 34/24 bushing, purchase the correct size:

I do have a micrometer now and it is a 34MM but not sure if i should get the 33Mm or the 35MM bushings for it since energy suspension doesn't seem to have 34MM bushings

 

energy suspension doesn't list a 34Mm only 33 and 35

 

The link contains has the correct sizes.

alright then, the bar is 34 or a little over everywhere except for where the bushings go, there one side is 31.6 and the other is 32.2 and there is no paint in this area. Do I get 32mm bushings?

 

anyone have an opinion? Do I get 32MM since thats the size where the bushings go, or do i get 34MM since thats the size of the bar everywhere else?

 

I'd probably go with 34, but that's me.
