A very long while back, in about 1982 I looked at a few M code 1969 Darts for sale. Larry Sheppard of Chrysler told me he was thinking Chrysler made about 200 of them. I found out later that only 1 "M" Code Dart was sold new in Canada and 4 "M" Code Barracudas were sold new in Canada along with plenty in the USA. If you would like to know a lot more there are "A" Body sites and Darts sites that can give good answer if the answer on Moparts are not enough.
