74 non-shock bumper brackets

I just compared 2 Sport bumpers and the outer pair of holes are way off. Inner pair are close, but may not line up. The single holes on either side of the license plate area won't have a place to run bolts through. That's the easiest way to tell the difference between std. & shock versions on '73 - '76 Dart Sports and Dusters. Tab extensions is the only mod that comes to mind at the moment unless you find someone to swap with.

There is only 2 versions of brackets that I've ever seen. They coincide with the frame mounting configuration. (Non-shock '73 & '74 are the same.)
