this clutch is for a 2003-2005 cavalier 2.2 ecotec it also has the slave cylinder kit too i'm sure it'll work in a cobalt too i bought this clutch in hopes to put it in my car but my car was wreck and caught fire three days after getting the clutch so i really need to get rid of it i'm asking $280 plus shipping give me a call or text at (928) 377-2127 and yeah i know it's bad to throw my phone number out but i dont have internet so this is my best bet
