Don't let this thread die!! I just got 404's for my 91 LS, I misread a thread, thinking I was getting 403's. Anyhow, I can deal with it and try to work it out or resell them and get something less agressive. What I'm looking for are strategies for passing smog, even though I've got 1.5 years until I'm up again. I'm thinking its time to start another thread specifically on techniques, we'll see.
