power steering and alternator belts

[jpliddy]

hi all i replaced the 2 aux belts today ,the 2 belts pass each other quite close about 3 millimetres apart they were about over 4 millimetres so always been close , can i safely move the power steering belt back some how say with washers on each fixing plate as the alternator can not be moved at all ,i have had the odd instance where the alternator belt can bounce and rub slightly on the edge of the power steering pully it only needs to move a few millimetres , has any one done this before ?
