If they know what they are doing, the emissions tester guys WILL look for the airrail and smog pump. Matt, you got lucky.
My 40 fails every year. The tags expired in September -- I'm waiting until January so that it will be 25 years old and I can get the 5-year plates (it's a 1981 model).
TJ, they shouldn't have put you on the rollers. Vehicles from 1981 and older require tail pipe emission tests only.
