From what I can tell with the side marker light its a 1970.... Did you look on the side of the hood to see what motor was in the car? Me and my dad built my first car. We started on it when I was 14 it was a 71 GTX w/ a 440... I sold it and got a 72 pistol grip 340 Cuda and still have it and in the middle of resto on it right now. My Dad also has a 1970 Challenger TA... Here is a pic of it and my 09 Challenger r/t I had before my truck.
