My second 1965 Dodge Dart.

The way I straightened the horn ring was perhaps a little risky I assume some will think. But I turned it upside down and placed it so where the spoke goes over in the ring was a little inside the edge of the table. Then I pushed down on the ring and released it, sort of to feel the strength of it. I moved the entire ring back in on the table to see if I had moved it at all, which I had not, then I moved it back on the edge, and tried a little harder. I took a hold of the ring a few inches from the spoke, and then in the middle, and then I placed the other spoke on the edge of the table and did the same. And used the same force.
That way it came a little by little, and finally I was satisfied with it. At least for now.
