I have a spare pulley off a 2.5na
It's off a mil one, so has the pulley for running the 12v alternator and a pulley for the 24v alternator but no pulley for PAS.
Yours for postage. Dunno how much it would cost to post, prob a tenner or so?
It's in good nick, only reason I took it off was cos I fitted a triple pulley for PAS.
PM me if interested
