1993 PGT, 199k miles, runs great. Need new accessory belt idler pulley that mounts on the alternator bracket. Every Ford dealer I talk to tells me it is the YS201. This is incorrect. The YS201 is a flanged pulley. The one on my car (original equipment) does not have a flange and the flanged version will not work. No one can give me a part number for an unflanged pulley. There is no number stamped on the pulley. There are no aftermarket pulleys listed at auto parts stores. Another potential option (but ridiculously expensive) is to get the YS202 which is the pulley and mounting bracket all together. However, no one can tell me if that is flanged or not. Can someone who has replaced/worked on this item please help me? Thanks.
