Thanks!

Ok heres a full break down. A pulley is smaller than the OEM pulley. Going to the dealer will get you nowhere as they have no idea what size belts you would need in order fit your new aftermarket pulley. If you can verify that AA has the same size pulley then i can find out the belt sizes like that.
The only difference between the years is the belt and by belt i don't mean size. I mean 08 is single sided ridges and 09 plus is double sided ridge. the easy way to do this is look under the hood if you see ridges then it is double sided. It is my assumption that you are not near the car. So PM someone from AA and they will tell you the belt sizes they use.
