Thanks

The U channel was bent to shape using high tech caveman tools
.
I started with a straight piece is the length that I needed and held it to the chrome part of the bumper to determine the point that the curve changes.
After marking about 11 of these points along the section, I went to the concrete stairs on the side of my house and negotiated the channel into shape with a hammer (do this part slowly and repeat as needed).
That's it for bending of the center support.
The side arms were notched with a jigsaw, bent at the notch and braced with a bar and rivets at the correct angle.
Piece of cake.
