I'm wondering if you could by any chance change the front end of the 73 scamp to a dart because the bodies are basically the same looking except the fender extensions
Two tabs on the lower part of the core support wont be there on the 73, these keep the lower valance from flapping in the wind. Also the lower bolt holes where the fender mounts to the core support wont line up. The turn signal pigtails are also different from 71 to the 73. Other than that everything else will swap without a problem.
