Anti roll bar bush size

[weinelm]

I'm looking to get some poly bushes for my front anti roll bar. Super Pro have various sizes ranging from 24 to 32 mm. http://www.fulcrumsuspensions.com.au/fulcrumCat/

 

Does anyone know what the correct size is for a non turbo 1994 SZ supra?

 

I measured it as 29mm, but 24 and 30 seem to be the popular choices on other sites (It was cold and dark when I measured... so I couldn't be sure)!
