Your grill is different, your hood is different. Your motor is different. The radiator mount is different. The front crossmemer is different. Your rear axle might be different. The dash and guages are different. The front splash pan is different. The tailgate is different.
Those are the things that quickly come to mind.
For most things Chevy parts are the same, but it is helpful to have a good idea which pieces are different.
