Good luck! I helped a friend to this to a 89 LX (4 to 8) in Colorado in about 1998. The issue is the emissions stations, CO uses the same outfit as down here, the problem is the visual inspection and the vin. As a 89 it was to have FI but instead a carb..."FAIL". Even though we put cats on they would run the test and even if it passed the stink test it would fail, and we would have to pay. So here it is, first check the AZ law on the visual inspn. If you car is a pre-FI car it needs to still have any smog devices that were on the car at the time. Me, buy the car if you can title and tag outside the emissions counties, still can drive it any where. In our case we took the car Idaho where there were no emissions, and used a relatives address, worked for us.
