            Fixed my belt squeal.

            This belt tensioner worked perfectly on my 2007 gt500, at a fraction of the cost. I had a terrible belt squeal, i changed this tensioner and it fixed the problem. Just regular hand tools and about an hour is all it takes. I am really happy with this part
