I actually have a box of metric bolts I've accumulated from various parts cars over time, I found one in there that worked. Just make sure whatever bolt you use is the right thread pitch (it screws in easily and securely) and that it screws in deep enough (lots of thread engagements, like 1/2 an inch) HTH

There is a bolt in the back of the battery tray I believe that threads down through and holds up some kinda harness bracket. I used that one with my slide hammer and it worked like a champ.
