When i was looking into it i was told i needed to get a piece of paper from an inspection station that approved the vehickle to be tested as what ever the paper said to test at. Up here in weld co. it is still new so everyone is sticking to there guns on this. There are only a few of these approved inspectors around supposedly. I will have to do this for the next project. The guy also said basically what uncle ben said on the years and what has to be on the motor. Those years are best because less equipment on them.
