Tried calling RockAuto to order an ACDelco harmonic balancer and pulley found out you can't call them they do not offer over the phone customer service..I'm not going to order a part if I haven't talked to somebody on the phone that can guarantee me it's the right part they have the computers that can match up and make sure it's right .I don't... Do any of you know a place I can order an AC Delco brand harmonic balancer and pulley from and talk to a live person that I can give my credit card number two??I've tried every part store in my area and none of them can get it
