back in the day, there were several airdams available for the 1st gen - stull made a 3 piece one with a rubber lip on it, hottops made 2-3 different ones, which Geronimo had one of until it caught so high pavement and I ran it over. That airdam has been repaired and my friend that fixed it could make a mold to reproduce it if there is legitimate demand for it. He also reinfored it from the original design so it will survive.
