I would strongly recomend getting another bolt from your dealer. I broke mine in half and temporarily replaced it with a grade 8 bolt of the same size. Only problem is the bolt i used was threaded all the way to the end and it caused all kinds of problems. It ended up stripping the block that the bolt goes through and i had to order a new block and it was a pita to get all of it out. Just go to the dealership and spend the 5 bucks or so to get the right thing.
