In fact, our first gen. Darts looks exactly the same as yours 1969 Darts, except for the instrument cluster that uses the Barracuda gauges, the sole 2-bbl. 318 V8 engine option and the four door sedan only possible choose for the 1969/1970 cars. Our Darts used front-disc brakes as an option only in the 1971 models too.
After 1971 year model more options could be found as I told before.
We had some brazilian-made changes only by 1973 with some cosmetic changes adapted to our local market, so by rule the 69/72 models were very similar to the 69 Darts in North America.
