M-code 440's were only made in '69. There were supposedly a total number of 1000 to qualify for super stock drag racing. The supposed numbers are 640 Darts and 360 'cudas.

I had no idea that there were that many m code cars made. I thought there were like under 100 darts made and I didn't even know there were cuda's too.

that would make 67 dart gts's and the 71 and 72 Canadian 340 darts way more rare.
