We have run into this situation before and gone over the inspectors head to his boss. The issue was resolved in our favor.
However, be aware that you may have to deal with the same inspector in the future and he will do his best to make your life difficult. I guess the bottom line is choose your battles wisely. Sometimes it's just not worth the hassle and time to battle with them........other times it's a big $$ issue and you have to stand your ground.
