I've found a couple and it looks like there's two, a level 2 and a level 3 that are identical in size, maybe one's supposedly louder than the other. I'm going to have to do this though. What initially scared me off initially was an article I saw that said you had to remove the bumper then I discovered that was for a UK model. LOL, I at least have a good 10mm socket and I'm convinced that size socket will dismantle 75% of any recent model car.
