2001 volvo s40 power steering pulley

hi guy! i just need a p/s pulley for my 01’ volvo s40 which is broken, but my local dealer won’t sell only the pulley without the complete p/s pump. this costs about $300. the mechanic who’s working on the car says the pump is ok, but i only need just the plastic pulley. used or new pulley will do either from junk yard or aftermarket. can anybody direct me on this? thanks guys.
