4 right and left mirror they have 3 bolts and a arm that comes up to a 5inch round mirror
5 right and left gravelsheilds for the rear bumper brackets
6 all the ac boxes under the dash not the hoses or the vents
7 all the ac parts from the outside of the firewall and the thing that goes in front of the radiator
