Below is a picture of the belt tensioner installed on Brian's truck. The 8 rib pulley will allow you to use it with either a 6 rib belt or the ever popular 8 rib balancer. The new tensioner has a stronger arm, and spring to reduce slip and breakage under the heavier loads produced at higher boost levels. Post up if you have any questions.
