got these from a guy on mustangworld and i don't need any more speeding tickets, so i'm selling them. i never installed them on my car, but they did come out of a mach 1 and have about 15k miles on them from what i'm told. i'll do $125 shipped on them from md. if anyone's interested shoot me an email, it'll be faster.
