74 non-shock bumper brackets

Ad asks for Sport or Duster, but Duster is different.

I have some '73-'74 regular Sport bumper brackets, just have to get them out for condition & more info.

I believe maybe 1/2 of the bumper carriage bolt holes will line up using standard brackets on a shock absorber bumper.

If I understand correctly, your old bumper takes standard brackets and your new one takes the shock absorbers, which bolts to the VERY heavy formed reinforcement?
