hi srt i checked out your post and found sb1224 expert cars built prior to 1981 of interest to me because i have a 77 wagon.couldnt get the ca. website to give me any info onsb1224. maybe you can find anymore info. for us ca. car owners it would be a great relif not to worry about smog every 2 years.sometime s you dont drive your pinto as much afraid putting on miles will wear something out and you would pass smog and not have the money to fix it. thanks for any help chris
