Went to install the new Jim Carter 4 core today and NO luck. It hits the fan blades.
I imagine they know about the little to no clearance on these long motor GMC's so figured the xtra cores they added would have been towards the grill , but looks like they went towards the engine side. Lucky I'm local to Jim Carter and sure they will take care of me one way or another . So looks like I will be searching for another option.
