“The first shipment I received was incorrect. I sent photos of the existing line and a photo of the line received. Second shipment was incorrect. I called and was told that they need more photos or I could request a credit. I've decided to attempt to rebend the line myself since no conversations are allowed with the tech department. This should not be a difficult line to duplicate. These engines were produced for 4 years by GM. I'm most disappointed in the lack of concern in resolving my problem.”
