That would have been early to mid 70's??
In primer with black front end? What form of "restored" was it? That was in the mid 80's and it was a in factory primer Dart.Hemi B bodies were 1/2 the price or less of the Hemi Dart then.
Friend of my dad's restored the Yellow Hemi 68 S/S Barracuda shown in the Anthony Young book "Hemi" in the mid 80's. Not many were restored to that level then. Of course the level of restorations have risen since then.
