Shiming the pwr steering pump out? Everything on same pulley?

[darkone]

hey all, my pwr steering pump doesnt line up with my mian pulley wheel. It lines up right in the middle of the 2 groves on my (harmonic balancer?) there is an extra unused groove in the main pulley (harmonic balancer?) but someone told me i can shim out my pwr steering pump to make the groove for the pulley line up with the one that the alternator etc is running on. is this a good idea, or should i keep on my hunt looking for a pulley that somehow recesses the groove of my pwr steering pulley back? any input appreciated. thanks!
