What we do with the repop bumpers/brackets is to put the bumper in the position we want it, heat the bracket(s) to yellow hot and then draw up the bolts. When cooled the brackets match the bumper perfectly. Keep in mind the arms (brackets) will no longer be spring steel but 99.9% of the stuff we work on will never use the bumper as a bumper again. If you forget, as we usually do, to do this before the finial finish is in place then drape wet towels across the gill/bumper/painted areas while the heating is going on. I've had some so far off that I used something like a long piece of 3/8 all-thread to draw the bracket close enough to use the regular bumper bolt for final positioning. On the S10 swaps we just use 1 3/4 x 3/8 cold roll strap for arms and do the heating and drawing into place to position both the front and rear bumper. Much easier and looks better than shimming or trying to cold bend spring steel to shape.
