its just the little black washer, this is for a idler puller asseembly for an 04 gto. All i can find is either just the idler pulley itself or with all the hardware, all i need is that little black washer. anyone might know what that specifc piece might be called or where to get one?
I bought a new pulley because this washer somehow dug into the old pulley bearing set and both got ruined. Napa had the pulley but not the washer....those fuckers.
