Hood and trunk lid interchange
I'm assuming the parts are for a '71 Swinger? Not a Demon. '70-2 Dart any body style hood will work. You may have to slot the hinge holes for more adjustment using a '72 hood on a '70-1 hinge. Trunk lid is '70-76 all Darts except for the Demon/Sport models, with the trunk lock being the only difference except for moldings/emblems. The Plymouth Scamps will work too, as well as the '74-6 Valiant 4drs.
