There was a Gen 1 Hemi Dart in a mopar magazine a few years back- it was gold and may have been on the cover. It fit. It worked. I think it is a terrible idea- please don't, but at the end of the day, it is your car to enjoy. A 383 GTS is a pretty rare car. Better to cut up a 6 cyl/318 Dart if you want a Gen 1 Hemi Dart. There are a million ways to create some eye candy on an old muscle car. Find a different path! Good Luck.
