Thank you very much the pictures helped me. the apron tightens to the bumper brackets. I didn't use the center bolt on the apron.When I tightened the other bolts the apron holes twisted up. I shimmed the apron out with a washer to better center the apron between the bumper and the grill and tightened the bolts and the holes twisted up. I'm going to take the shim washers out they didn't help. Should I mount the bumper brackets first? How do I keep the apron holes from twisting when I tighten up the bolts?
