they were made by mopar performance, yet were discontinued.. yet you can still find some lying around new. MAS fiberglass also makes front spoilers, buti havent seen one on a car yet... i dont know how it is... they're only $50 (they run ads in mopar muscle)
i dont have one on my car... but i took alot of pics of a duster that had one in englishtown if u gimme ur email i can send them to you.
