Thanks guys. Yep a little while after I posted I was at the point of actually getting the main body of the brace up in there and yep realized the only one that could fit in that top right location was the shorter factory bolt.
I can't find it now, but on this site I had a link which I saved the tab for days where it had the instructions for putting the ID Speed brace in. They are absolute garbage. So many details left out, and it bothered me so much that I took pics and am thinking about re-wrting them for the benefit of others after me.
Got it in though, it rules and I can tell a difference. So great to be able to rage on this thing finally!
