Frame Horn Help Please

[Dale99]

So the previous owner bent the ends of the front frame horns out to make space for a custom front bumper, even cutting a section out on the drivers side. I'm trying to bend them back so I can put a stock bumper back on. On the rear, the bumper was twisted 10 ways from sunday and in the process looks like it bent the horns on the rear. I am thinking they need to be square with the frame?

I was wondering if someone could get me dimensions as to how these should be placed, as well, take some up close shots of stock ones so I can see what they should be like.
