1997 PAU Serpentine Belt Replacement

I just had a Tensioner pulley blow out on me and partially destroyed the Serpentine belt on my 1997 Park Avenue Ultra. I was wondering if anyone had ever changed the serpentine belt on a PAU. The belt appears to go under the engine mount in two places (basically around and through), and I can not figure out how to change it. I have already taken most of the Mount off and still can not get the belt through the mount.
Any help Would be greatly appreciated.
Thanks

Click Here (http://www.automotiveforums.com/vbulletin/showthread.php?t=882294) for info on belt replacement. Be sure to inspect the "hidden pulley" (#9) down below the tensioner and behind the mount. In fact, I just went through the same thing on my Ultra several months ago, so I replaced all idler and tensioner pulleys, with both belts at the same time. The front mount will have to be removed for the lower pulley replacement. In addition, the PS pump will have to be set aside to get the mount off! If you replace pulley #9, the motor will need to be supported with a jack and a piece of wood underneath. While everything is loose, jack the motor up some, to get the mount out. If you don't have the tools for the job, it would be better to take it to a trusted shop. :)
