Better front bumper fit on a 73 Sport

Why not try and retain some of the shape. I think a '73 Plymouth Duster/Valiant/Scamp bumper would work a bit better.

It still has some of the peak shape, but not nearly as much and would be a direct swap.

Isn't a 73 Scamp, Valiant, Duster bumper the same as a 73 Dart? They look so similar I've always thought they were the same.
