D/Darts had the 275hp engine. It would not quite be decked out like one (they didn't have the chrome air cleaner due to the Holley carb). The "32" under the "AB" indicates a 273 four barrel. In order to be a D/Dart the VIN must read "LO23". EVERY V8 in an A-body in 1966 has a "D" engine code as the only V8 available was the 273 in three flavors. The 275hp version was only available in the D/Dart. To my knowledge they were also white with red interior, four speed, no console, 8-3/4 with 4.56 or 4.88 gears (I can't remember which).
