Hi all, My son introduced my 03 Grandprix GT Limited edition to a fire hydrant. Luckly he only broke a headlight assembly, and caused some scratches a lebra will cover. Heres my question, should I replace both assemblys as the car is 9 years old. Meaning do you think there will be noticible discoloration? or should replacing just the broke one be O.K. Has anybody out there changed just one assembly?

David.
