it is a windsor. the cleveland has been out of production for many years now. the thing to do is to look up a picture of the alternator for a 86 grand marquis and see what the pulley on it looks like. just go to http://www.autozone.com and see what thier picture shows. that will tell you want it is suppose to be. wait here it is.
