There is nothing the hold the cooler in place except the boost hose's! there should be 3 brackets though,1 for the top of the rad and 1 for the botom,then the other is to move the fan across and use the original fan mounts on the rad. You can buy the fitting kit from Pace but it's not to hard to make up some brackets yourself!
The cooler itself is not that much better than the standard item and if your running over 14 psi of boost is pretty useless!!
