does anyone know where i can get a replacment power steering pulley for a 1992 sc300. yesterday it just fell off when i was getting gas, i think the ball bearings or something broke and now i cant get it to stay in the pump. can i just get a new bearing for the pulley or do i have to buy a new pump and pulley, pulley seems fine exept it doesnt stay in

 

went to an autoparts store and they said they could get me a new ps pump for 130 ish i didnt think that was that bad but i dont know if the pump comes with the part that broke on the pulley. anyone that has bought a pump from these stores get a ball bearing for the shaft to the pulley.
