how many dart generations are there?

i dont know ......they are completely different cars .:tongue7: Nothing interchanges except driveline and inner fenders ......there is even differences in floor pans

I said they were 'virtually' the same car LOL if you take side view pictures of Darts from 67 to 76 and take your thumbs and cover the very nose and tails, the only real outward differance you would see would be trim and a wing window (or no wing window) .. the cars would all look the same... which is exactly why people who want a 70 Dart convertable (which they never made) can have one.. take a 69 drop top Dart, put a 70 front clip on it, and change the quarters and you have a 70 Dart convertable (I realize there is a bit of fabricating to do in inside the trunk area as well but....) .. I have also seen people take 73-75 Darts and make them appear to be 72's... So to me. they are all 'virtually' the same LOL
