The 70-73 and the 74-76 rear body panels will fit 70-76 Dart and 74-76 Valiant 1/4 panels since the later
model Valiants are based on Dart body. The 1/4 panel extensions are different between cars with tail lights in body and ones with tail lights in bumper. The 74 -76 cars also use the big impact absorbing bumper shocks. Rear trunk floor
should be the same.
