1973 Dart Bumper Assembly

When I bought this car, it came with numerous bumper supports and brackets and two newly re-chromed bumpers.

The problem is that I have no idea how to mount them. I have no idea what piece goes where or where it bolts to on the car. I have looked at some tech manuals but they haven't really helped. Does anyone have any pictorials on how to do it, manual pics, etc? I have no idea how many bolts I need, what size, etc.
