I'm currently looking for a 68-73 Dart so I'll be educating myself
on these cars reading through all the threads here.
I'm also on the Dodge Charger forum asI own a NM '69 440 R/T.
Welcome, this is a great place for information! If you don't know, the 74 dart is identical to the 73 model, and the 75-76 is very close - slightly different in the grill. The 73-76 cars generally sell a little cheaper and the selection is a little better.
