The exemption tag is on the hood itself,on the driver's side.It has all the options/equipment and vin on it(so you can't put it on another truck).In Vancouver i still had to go thru emissions and pay the fees,but pass or fail i still got my tags.They just wanted the fees! I had to argue with them everytime about it being an exempt vehicle.That's why i bought this one over an 88 i found at the same time.With that tag i can do what i want with it for mods and not worry about emissions.
