Front bumper assembly

good afternoon,

I’m assembling my front bumper : I have 4 big lead washers, one rubber washer, one curved iron washer (fits on the upper -set of three- steel layers), and two small iron washers to fit on the rubber washer.
I only need to use the lead washers to ‘fill’ the curved ends of the bumper. Can someone give the correct order of the washers to assemble the front bumper
