I wouldn't hesitate to order a radiator from RockAuto personally. You can get damaged items from anywhere. IMO that's really more of a courier issue than a vendor issue. Every courier (USPS, UPS, FedEx etc) has areas of the country that employ some gorillas who are more destructive than average when it comes to throwing boxes onto trucks.
I don't think it was the courier. The two damaged radiators I got through Rockauto were delivered by Fedex. The radiator purchased through Amazon was also delivered by Fedex. It's possible that it was Fedex's fault, but I'm more inclined to blame the thing that changed, not the thing that didn't change. If Rockauto suddenly had a Delphi 1215 in stock (it's discontinued) I'd try them again, Though.
