Guys, Got a Mag and am in need of a new drive belt for the machine as the old one is getting frayed and stretched out. This is not a smooth belt but rather a notched belt. Does anyone know what the Gates # is for this belt? I know if I call PG the belt may not be too expensive but it will cost a load for shipping. I figure some of you Mag owners just get your own belts so may know the #. Thanks!
