If it fits on your EG Bolt On and you're using the OEM Endlinks, its more than likely an ITR Sway Bar.

It's simple, get a Crescent Wrench and tighten it until the bar fits in there tight. Remove it and measure with a Ruler the opening from the Wrench and you will see if its 22mm or 23mm. You cannot tell by just looking at it, you need to measure.
