Whiteline Swaybars

[72marinablue]

I have been searching the web trying to find some whiteline swaybars. I am specifically looking for a 24mm rear irs bar for a 72 standard. All the resources I have tapped say that it has been discontinued. The biggest rear bar that aircooled.net is selling at this point is 18mm and it is non adjustable. The bars will be going on my daily driver and but I would like to run some occasional autocross events also. Any idea's?
