You are probably going to need to fix the radiator support and get the headlights taken care of. I am not sure how they do it wherever you are from but they basically want everything perfect and safe here. Since the headlights will be out of alignment because of the rad support I would imagine that they will want to make sure that is straightened out to pass. I am not sure how much the inspection will cost you but at the worst they will fail you and tell what to take care of in order to pass. You could also pay a body shop that repairs totaled vehicles to do an inspection and let you know their opinion as they should be very familiar with what is necessary and what they will usually let slide. In the end though it all comes down to the inspector. Paying a body shop to look it over is probably cheaper than paying for 2 inspections, at least here in CT
