I have a 73 Dart Swinger Hard Top and can verify what 72bluNblu showed you.
I would build brackets to attach the shock style bumper to the sides of the rails if the bumper is worth using.
That way if you used the holes in the rail sides like the 73 and down uses, you could always take time and patience to find a 73 bumper and brackets later.

It wouldn't take much to make brackets that attached to the old shock mounts on the bumper and the side of the rail holes.
Then slot those rail side holes and you can adjust the bumper in and out where you like it.
