I suggest checking the federal law regarding emissions standards. Once you know what you are talking about then you are welcome to criticize my comments. Your question already wreaks with automotive ignorance so its no surprise than you would be defensive and agitated at my response!
Wasn't the first model year Lebaron 1977? I couldn't even find a '72 in the books. Must be a real rare and special car and since there isn't anything in the books than I guess your right. If the car doesn't exist than it doesn't have to meet any emissions requirements. I apologize!
