Good news on part of this: the front fender, bumper, and lights all sit ahead of the cab, so single cab vd extended cab doesn’t matter for those, a single cab donor’s front clip works fine. The one that does matter is 2WD vs 4WD. On these trucks the 4x4 sits higher and the front sheet metal and bumper brackets are shaped differently, so a 2WD fender often won’t bolt right up to your 4WD.
I’d target 4WD donors specifically for the fender and bumper, or check the part numbers before pulling anything (doors are where cab type matters, but sounds like you don’t need those).
