Dart GT was the premium Dart in any year made. More trim and standard options. 111" wheel base Hardtop or convertible (all convertibles were on the GT platform
Dart 270 is a step down from the GT but the same body, just different trim. No finish panel on rear but had the 4 pieces of trim (THAT I NEED BY THE WAY) The GT has trim at the top of the body line, 270 trim is down a few inches
