Kudos for the writeup.
I do have a quick question. While mine is not off the car yet (waiting for the bushings to come in) I can't see it first hand yet. But would it be possible to use a flat head bolt similar to stock with a small weld instead of the nut and bolt? It seems like you could eliminate any clearance issues and any worries about the nut ever backing out. Forgive me if I'm totally off track but like I said, it's still on the car so I'm just throwing out an idea.
