Run something oem or something else that would be an acceptable vibration damper. Ther are some decent fluid dampers out ther but they are pricey. Personally I'd just find some oem one with some chips on the ps pulley part and have it machined down to just the alternator and rebalanced. On my car I machined off the ps and left the ac.
