The hood pins can range from $15 to $80. Do your best to find a reputable company. In the future I will be able to help a little more with this.
As far as do you realy need them. Well its peice of mind that your hood will not fly up when driving. High speed driving will put alot of stress on that latch and could fatique it. I can't say right now the durability, but you may be fine and never have a problem. Its up to you.
