Joerg,
I believe they should point upward just a bit. What I would do is use the frame horn as a lever for straightening them first. The two bars are joined by a rivet about where the arrow is on the attached pic. I believe they point straight forward until that rivet. I do have a set of repop bumper brackets in the box that I might be able to measure for you.It would be easier than measuring on the my truck, because the weather is getting nasty and the apron is in the way, requiring laying on the ground.
My original front bumper brackets were trashed, but I was able to find a good pair at a wrecking yard.
Let me know if you'd like those dimensions.
