Chin spoiler damaged.

I knew it would be prone to scuff and cut up some on the underside of the spoiler at how low and protruding the chin spolier is but was really mad at myself with how easy it actually cracked open and now i need to replace it my question is has any one had to replace their chin spoiler and if so how did they find getting the replacement from their dealers. First dealer i contacted knew absolutely nothing about this chin spoiler ,,and he told me there is no part # for it. Just a lazy parts guy . Second dealer was more helpful and i got the part ordered. Any one else who has replaced the spoiler on account of curb damage or whatever?.
