If you click on my signature you will find a picture of my engine bay. I have flipped the tensioner over using the March brackets, eliminated the AC and air pump.
But, the motorsport bracket should work just fine. I would check the alignment and tension. The tensioner has a range marked on the face of it, see if the pointer is within the range.
Hope that helps.
