Duster rear bumper question

Burnt,
one of the things that I noticed with my '73 is that the angle of the rear sheet metal and the bend of the rear bumper are slightly different. The gap is smaller in the center and opens up slightly twoards the outsides. This is the way it came from the factory. As you know I have done alot of work on my back bumper, but because of the amount of work needed to get it right I decided to live with that flaw.
Other than that your bumper looks like it fits like mine does.
