1974 Dodge Dart Sport
I don't think they still had the 340 in 1974 so someone swapped that one in.
No matter, these cars get modified and parts get replaced all the time. I love all the Dusters, Dart Sports and Demons. I've had a few myself.
Here is one of mine....a 1973 that was an original 340 model that I bought as a roller:
The wheelwells were radiused for some reason. The fenders were replaced so I replaced the quarter skins too.
I am not usually a fan of body colored bumpers with the exception of black cars.
I tucked the bumpers in as tight as I could do.
This one was sold about 7-8 years ago.
Cheers!
