motor mount help

[Gambino]

So I have had my AWR motor mount on for some time. while moving my car from az to ut, I misplaced the bolt that goes through the circled area

I bought a new bolt from a hardware store, but it isnt working so well. I can hear loose hardware when I start and stop my engine. Also, I can move the engine around fairly easily with just one hand. Does anyone know where I can find a new bolt that will actually work? Thanks

go to the dealership i am sure they can help you out. usually the people at the parts desk take it upon themselves to find the hard to locate parts like that... at least in the few instances i have had at different dealers they take it like its a mission lol...
