I would remove the entire front clip as a unit. You will have less chance of damaging paint. There are just too many fasteners which are difficult to get to in order to give you room to pull the engine. There is information that indicates that GM assembled the entire front clip as a unit off of the truck, then installed this unit on the truck.
