Rear Contour Bumper Fitment?

I just scored an original rear contour bumper for my 83. Unfortunately it doesn't have brackets and those seem to be made of unobtainium. Does anybody have a good pic from the rear or side of where this bumper lines up? Not even too many good pics of these on Google. Thanks.

I believe fellow forum member Reamer makes the brackets for these bumpers.

Thanks... sent him an email.
