Does a original 75 dart swinger with a 318 have EGR?
Worse yet, on the first couple of years, you CANNOT tell by just looking at the external engine. The first couple of years, Ma simply drilled "leaking orifices" in the floor of the intake, right into the exhaust crossover. Only way to tell on those early cars (72, 73?) was to remove the carb or open the throttles and look inside the manifold plenum
