I used the Moroso ones that are in the Summit link above(local speed/machine shop carries them) and they worked just fine. I know they say for a 3" tube but they fit my 8.8 perfectly. If not a little grinding should open the radius up just fine. I like the fact they are very low profile. Which is nice if you are staying SUA.
