These are the parts that make a front-end repair a bolt-on job rather than a panel-by-panel rebuild, and they are trim and option specific.
Complete assemblies are the right answer when the cover, grille, absorber and brackets have all been disturbed together, or when the original is a one-piece composite front end. They are trim and option specific, and the mounting provisions on the body rail are what decide whether the assembly sits square. Check the reinforcement bar behind the assembly before fitting.
