In order to repaint the bumpers right and have them match perfectly, you gonna have to take the bumpers and extensions off and blend the color into the fenders, hood, and rear quarters and at that point you might as well re clear the doors, side skirts and the truck lid. If you just paint the bumpers they wont match. I do body work for a living and we never have a perfect match to "panel" paint (to not blend). Blending the color is the only way to make it look perfect.
