hello, i am doing the same thing, i wanted to replace the belt and idler pulley. mcnews have both but nothing of the aftermarket type deal,they carry the stock oem stuff. they said that there is no need to upgrade them, besides no body that i could get a hold of makes an aftermarket kit. so, we'll have to go stock! if you find anything diff out there, please let me know or post it. txs. yannio
